I have 3 biowheels running in this tank in addition to all of my live rock. It is likely that these are the source of the nitrate so I'm pulling them out. I'll need to rely on the live rock to perform all of the biological filtration from here on out. If this coupled with more water changes doesn't lower the nitrates I'll have to add a refugium with a deep sand bed and macro algae.

I was carefully watching it extend extremely fine filaments from the underside of the coral. I had noticed these before and thought is was just another small worm living in the tank. However, after studying these long enough I realized that these were tentacles and the coral was feeding. You see, the coral would let these out and would let them drift about. The coral would then rapidly reel them in. Look closely at the first photo below because the tentacle is difficult to see because it is so fine. Each tentacle has one main strand with small "rungs" hanging off of it.
These tentacles appeared to be able to extend 4 or 5 inches beyond the edge of the coral. My green open brain was in stinging range of these tentacles so it got moved a few inches further away.
Here are a few more pictures of my rose brain coral.

The Pom Pom Xenia is still in the process of splitting. Unfortunately, it isn't looking that great. It is starting to shrink a little. The polyps are much smaller than they once were and the stalks are a little shorter than they were a couple weeks ago at its peak. I did a water change last week in hopes that things would get better. I haven't really seen an improvement yet though. I'll do another water change this weekend. Here is what it looks like today, May 14th.
Here is how it looked one week ago on May 7th. Look how the polyps were so much bigger. This is bad Dory.
I also added carbon to my filters to see if this would make an improvement. So far I haven't seen any change.
In other news my Toadstool leather is always flopped over in the morning but then straightens up during the day. This didn't start happening until I added the Colt coral. Interestingly it leans exactly in the opposite direction of the Colt as if it is trying to get away from it. I know that the soft corals use chemical warfare against SPS corals but I didn't think that this affected different soft corals. I added carbon over the weekend to clean up any chemical toxins just in case. As of yet I have seen no change. Maybe it just likes to lean over to sleep. It looks totally fine during the day and molts every few days.

Here is how it looked when I bought it. It had only a single short stalk.
The coral now looks like this. The two stalks are now in the process of splitting completely in two.
The taller stalk appears to be starting to split also. Looks like the whole process will repeat itself soon. Some people complain that these things can grow like weeds. I look forward to the day I can prune these and perhaps trade the frags for some different coral.Meanwhile, my original Xenia has completely disappeared. I examined the rock it had been attached to and couldn't find a trace of it anywhere.
