The orange coral is a capricornis recovering from being recently fragged. The concern for it is keeping the star polyps away from it. Star polyps are capable of stinging lots of SPS and LPS corals.
In the center background is a colony of Sinularia that is struggling to recover from hypersalienty while back. Note the seashell in the upper right corner. It is separating the Hydnophora and Pocillopora. The Hynophora was sending out sweeping tentacles and stinging the other corals. My mistake was gluing the frags so close together. Horn corals need lots of space.
This Halimeda showed up on its own several weeks ago. It has already been thinned a couple of times. The challenge is to keep the calcium level normal during this time. It has been suggested that it will out-compete the Caulerpa but so far the Caulerpa is still a nuisance!!
The mushrooms in this tank have really multiplied over the past few months. The Xenia are also doing very well. They are the same as the ones in reef A but for some reason are darker and pulse more.
The Lighting in Reef A is MH 10K K at 175 watt. In Reef B there lighting is PC 4X55 watts also 10K K.
It is feeding time and every critter has come to be fed. Nowadays both Neon gobies only come out during feeding time. Not sure how the Neon goby out in the open lets the other one o food is available. The lower fish is just above the hole where they may have a nest.
