Reef Builders appears to be on an enviable field trip to Live Aquaria's coral facility in Wisconsin. Having grown up around various aquaculture initiatives that my dad was involved with, I've got an appreciative eye for the fish lab. And you don't get much more high tech than Live Aquaria's coral setup.
Like the smart bloggers that they are, the trip has been broken up into a half-dozen bite sized posts. Here are my favorites:
This post was supposed to be an update on the new corals and fish I added a week ago, but first I'd like to introduce you to Boris the Destroyer, a superglue eating hermit crab:
The first inhabitants to take up residence in my tank were hermit crabs and snails, including Boris here. While the rest of the hermits are fairly mild-mannered, Boris is a special individual. At some point in the past year, he killed a Nassarius snail, took over the shell, and promptly grew to three times the size of his fellow hermit crabs. I've always wondered how he managed to grow so fast, and why he shows particular interest in new coral additions to the tank.
It turns out Boris has been eating the super glue (Cyanoacrylate) that I use to attach coral frags. Over the past week, each morning I've awoken to one particular Monitpora frag knocked loose from the rock work. I'd reattach it, only to have it knocked loose again the next day. Each time I re-glued the frag, Boris would make a beeline from anywhere in the aquarium straight to that coral. I thought he was picking delectable treats off the foreign frag plug, but after a few days I realized he was actually chipping off and eating the super glue. There can be no doubt that he has gained super powers from this diet, and poses a threat to civilization.
I had banned the naming of aquarium inhabitants ever since a pair of cichlids my girlfriend had named after F. Scott Fitzgerald characters were found floating upside down, but as Boris is surely immortal, I have no problem bestowing him with the name.
The Plectranthias inermis is doing great. Although still quite shy, I have seen it venturing further into the open. I was worried about how small it was compared to the other, more boisterous fish, but everyone seems to be getting along well.
The corals were, as usual with Live Aquaria, healthy and attractive frags. I noticed what could possibly have been STN setting in on a nub of the blue branching Montipora, so I snipped that off. The green branching piece took quite a beating, as it was a target of Boris, but seems to be recovering decently. The green cap is also good, although I am considering moving it to a position with more light.
You can also see in one of the following photos how insanely fast the Montipora caps I got a few months ago have grown. They have easily doubled in size, and one is moving in on its neighbors. I am hesitant to mess with success here, but something may need to be moved soon.
Fresh off a plane ride from the Live Aquaria facility in Wisconsin:
Plectranthias inermis (Geometric Pygmy Hawkfish)
I have been following the Diver's Den RSS feed for a few months, waiting for a unique fish suited to a smaller reef aquarium, and I'm hoping this will be it. Given my recent issues with nitrates, likely from heavy feeding, this will probably be the last fish I introduce into the tank. As such, I was looking for a lively and interesting specimen.
Montipora sp.
I have had great success with the growth and general health of Montipora species in my tank, especially when compared to other stony corals. Hopefully these new specimens will do just as well. All of these corals were grown in an aquaculture facility, while the fish was likely wild caught.
A little over a year ago, on my first trip to San Francisco, I stumbled into a temporary aquarium space for the California Academy of Sciences. They had an enormous, two-story coral reef setup, along with an aquaculture facility for propagating more corals. Talking with the staff informed me that the tank was a test to see if coral could be grown in captivity at extreme depths, and the propagation facility was for growing out colonies to populate a much larger tank that would be located in their permanent building, scheduled to open late in 2008.
Being out there for business this week, I took advantage of a few spare hours to get over and check out the finished tank. Unfortunately there wasn't much stocked in the form of corals yet. I'm not sure if they are adding species in slowly or what. There was an enormously large and diverse population of fish however, along with some other innovations. A large sand bed with a full grown mangrove tree was attached to the aquarium. A walled off section for sharks and rays, as well as a shallow lagoon area was also attached to the tank. The reef tank is impressive in size and ambition, but as all reef keepers know, it will take several years to reach it's true potential.
The california coast tank was also quite large, and featured an enormous wave box. From what was visible, it appeared to work on the same principal as the systems common to home aquarium. But check out the size of these waves:
My favorite section of the aquarium was the staff picks. Here small aquariums and terrariums were set into a wall, featuring a favorite species or biotope of each staff member. There was an incredible reef tank here, with a coral wall built along the left hand side leaving dramatic open space through most of the tank. Very cool.
Below are some photos I snapped, and there are a few more to be found on my Flickr account.
My favorite tank design:
Primary viewing window for the reef (there are several others):
Some of the reef lighting. There was another tier of lights above this, as well as natural sun lighting through the roof:
I absolutely love ordering from Live Aquaria. They have the best service, a wide range of livestock, and great shipping. There is one part about ordering from Live Aquaria that can trip me up though: they have two different facilities. One is in Wisconsin, and seems to be primarily for aquacultured coral. The other is in California, which I imagine handles imports from the Pacific. This time I based my order around the fish I wanted, and filled it out with other specimens available from their California facility.
My reef has only had three fish for its first six months: our resident firefish, who was the original inhabitant, and the pair of clownfish I added at the end of summer. While moving slowly on additions is always a virtue with keeping a reef aquarium, I decided it was time to move forward with a group of fish I've always wanted to keep: Chromis viridis, the Blue Chromis. The layout of this tank was originally created to allow for a large open swimming area at the top, specifically for small schooling fish like the Chromis. I purchased five juveniles, which will hopefully adapt well and add a lot of colorful motion to my aquarium. As nice as corals are, you really can't beat the visual appeal of a group of colorful fish. It makes the tank appealing from across the room as well as close up.
Below is a full list of what I ordered from Live Aquria. I also purchased some coral frags from a member on Reef Central. Both orders should be arriving Tuesday.
I wanted to provide a quick update on my reef aquarium. For the most part things are doing well, and I feel like the tank has established a good rhythm. Water quality has been great, the firefish has been quite healthy, and a plethora of small invertebrates has been emerging from the live rock.
Coral Growth Of the ten coral specimens I've introduced to date, eight are doing great and showing good signs of growth. The Acropora millepora and tabling Acropora in particular have shown exceptional encrusting growth lately. The pink birds nest, Stylophora pistillata, has also been growing very fast.
Two species not doing well. The Pavona maldivensis has been pale and showing no sign of growth since within a few weeks of being introduced. I keep hoping it will come back, but it is seeming less likely with each passing week. More concerning is the recent demise of the Pocillopora damicornis. For the first month, this was my healthiest looking coral. Great color and polyp extension, and very obvious growth. One day it just started going down hill for no apparent reason, showing bleaching around the base which has since spread up into the branches. Some of the polyps still look healthy and extend to feed, but I fear there isn't much time left for this colony.
Flow Adjustments I decided that running two Koralia 3 pumps, 850 gallons per house each, was too much for this tank. Corals demonstrated stressed behavior in the powerful current. I have since cut back to running just one, with a Koralia Nano on the opposite side to keep detritus off the bottom of the aquarium. This seems to be working out well so far.
Zeovit Possibly suckered in by the great marketing photos on Zeovit USA, I've started to implement their system on my tank. Zeovit is a mineral that has been commonly used for filtration in commercial aquatic systems prior to becoming a trendy brand in the reef hobby. The pore density of zeovit makes it exceptionally good at filtering out ammonia, preempting the nitrogen cycle before it can occur. By removing the ammonia early in the cycle, bacteria never get a chance to convert it into nitrite, which eventually becomes nitrate.
Because of the sheer effectiveness of its ammonia removal, it is suggested that the reef keeper dose colonies of bacteria and bacteria food to keep the tank in a natural state. Conveniently, the provider of zeovit also makes these products. You can read more from the source in this PDF guide to the Zeovit filtration system.
To start, I've begun with ZEOBak bacteria solution, and the ZEOFood7 bacteria and coral food. I will slowly introduce the zeovite filtration material this coming week. There are a number of other supplements and foods in this product line that I have read good things about. Although too early to make any sort of useful evaluation, I've noticed the tank water appearing quite a bit clearer since the dosing start. Algae formation on the glass also appears to have been reduced quite noticeably. I like to pretend that the corals are beginning to color up and appear healthier as well, but that could just as easily be attributed to their finally becoming acclimated to the tank.
When I came home from work tonight the firefish was out front and center, and he's been at the glass begging food and attention ever since. I managed to get some decent pictures of him (her?) and the new coral:
Today we took a trip over to Skipton's and looked for a good first fish for the reef tank. As a person with a history of past impulse purchases, I wanted to make sure I limited my selection to species I had read about and knew would be good fits for my tank. I made up an email with common names, photographs and scientific names of the six fish I was interested in and mailed this to my iPhone. This turned out to be really helpful when staring down the tanks full of gorgeous saltwater fish.
We ended up deciding on a Purple Firefish, Nemateleotris decora. Here is a shot from when he was drip acclimating.
Quite the looker, and the colors are even more vibrant under the metal halide lighting. Its been hiding under a rock on the side of our tank for the majority of the time so far. I saw it eat a few marine food flakes that I dropped in experimentally, so hopefully all is well and its just being shy/angry about the new tank. I also picked up some frozen food while at the store, mysis shrimp and a marine blend. Once I see this guy show himself around the tank I will try out a little of that.
I also couldn't resist getting this Zoanthus colony. I've really wanted some polyps for the tank, and they were too nice to pass up. The polyps are most closed up in this photo, I will take a better one tonight showing its placement in the tank.
With the new metal halide lighting in place, I wanted to have someone take the compact fluorescent fixture off my hands. A one bedroom apartment is not the sort of place that you tend to keep unused equipment sitting around in. I posted listings on the aquarium forums I use, and on Craigslist. One interesting note came in from a Boston area reefer who offered up some coral frags in trade for the light, in lieu of the price I had been asking for.
Throughout the entire history of this project I have tried to plan and move slowly with each aspect. Impulse purchases and stock acquisitions can be a real problem with keeping aquariums. The prudent move would be to watch the corals I introduced on Friday carefully for two weeks, and then proceed with further stocking. Furthermore, the corals being offered in trade are some of the more difficult of the stony corals to keep. I decided to get them anyway.
Here are some photos, along with trade names and my best guesses at scientific names.
Acropora rosaria:
Acropora sp., "purple slimmer":
Acropora sp., supposedly a tabling formation:
Acropora millepora:
I acclimated these with the same slow drip procedure used for my previous coral acquisitions. So far everything seems at home, with decent polyp extension. I think I'm close to my limit on coral species and space in regards to the room they will need to expand into over the course of the year. Now the long wait while they slowly fill in.
Here are the first corals to hit my tank. All are aquacultured fragments of larger colonies that have been thriving in captive conditions. This makes them more likely to survive in a new aquarium system compared to wild caught specimens, or so I'm told. In the future I will hopefully be able to write up in more detail the particulars of each species, and hopefully figure out how to take some better photos. I'm afraid that last part might involve some expensive camera equipment.
This morning I placed an order at Live Aquaria for a stony coral frag pack. While stony corals can be more difficult to keep because of their increased need for light, calcium, and water current, I find them some of the more interesting species and was what I always envisioned keeping in my tank. The package I ordered is for five frags (small fragments from a larger colony) of aquacultured coral colonies. Aquacultured specimens, as opposed to wild card, are purportedly more tolerant of aquarium conditions and less likely to be severely traumatized by the introduction to a new tank.
My new metal halide fixture arrives tonight as well, so I hope to be able to get that setup and post pictures of the tank. This should represent the last piece of equipment that was part of my original tank plan, although I've already thought of several things I'd like to change and upgrade in light of the decision to keep stony corals primarily.
