Live Rock Addition

Yesterday, I added a large live rock to the main tank. The rock was in quarantine for 6 weeks because it came from a tank that had an outbreak of fish parasites. It took me hours and hours to move corals out of the way and get the rock situated. I tried my best not to break corals and scratch the acrylic walls of the tank. But, it was not easy to avoid.

With the new arrangement, I wanted to move one of the Vortech pumps higher up to provide more water flow in the tank. In doing so, I changed the dynamics of the tank and had to rearrange other corals that might not like as much flow.

I still can't find a good place for my red Gonipora!

Moving corals is like playing a game of chess. You must strategically place your pieces and decide which ones you value the most. And, if you're not careful, a pawn (a colony of zoanthids) can easily take your queen (Acropora).

Rather thank taking pictures of the boring live rock, here are some shots of the right and left side of the tank.

This purple Acropora nana is about 6-7" high and attached to a 3" high rock. I found a new place for it, but in the process, I broke off some tips and tore off tissue from the main branch. I'll have to wait and see if it recovers or goes the STN or RTN route that usually strikes less robust corals.

Acropora gemmifera

These frags of Acropora gemmifera were purchased on 6/1/09 and entered into a "growing/survival" contest at SDReefs. I treated the frags with TMPCC coral dip according to the basic instructions. Some inanimate flatworms were observed after treatment and I wasn't able to detect any egg masses. The frags were placed in my refugium under PC lights for about 2 days before I mounted them to live rock using AquaMend. On 6/6/09, I noticed tissue recession at the base and decided to re-frag and remount all frags to avoid any more STN (slow tissue necrosis). This time, I used a cyanoacrylate gel to glue the frags to the rock.

The frags are now in the main tank under LED lighting. I still see some tissue recession with some of the frags. I now have 7 separate colonies and will just have to wait and see which ones survive. I was limited to where I could place these frags, so getting the best pictures was difficult.

Corals, Amphipod and Sea Spider

Who says you can't grow SPS corals under LED lighting? In the background is a flourescent green "acorn stag" Acropora sp. and in the foreground is an A. valida coral. I originally had the green stag mounted alone on a rock, but a portion of my wildly growing A. valida grew onto the same rock and declared war at the base where they met. Several months ago, I moved the rock to a higher location in the tank and broke the connecting coral. Today, I dislodged the rock and turned it around in order to show more of the A. valida. And, because it is positioned closer to the LED lights than the mother colony, the polyps are more colorful.

This variability in color quality as a consequence of lighting intensity is a similar property in reef tanks using metal halide, T5 or PC lighting. So, one must figure out the optimal placement for each coral before committing it to its permanent location.

This amphipod was found in between the glass and the Subcurrent filter in the Nano tank. I wanted to get a clear picture of it because of the fore claws. I can see how it can easily be confused for a baby Mantis shrimp. Although, I should do some research to see what a baby Mantis really looks like!

At the base of a Devil's hand leather coral, I found this sea spider. They have a bad reputation for feasting on soft corals and prized collections of zoanthids. I really wouldn't mind if it mowed down the uncontrolled yellow zoanthids in my tank. I shouldn't take the chance and find that a mate is ready to do some serious multiplying. So, I'll have to extract it soon.
