Sorry, 29g FOWLR tank, maybe converting to reef in the next year. I have some zebra hermits, and some scarlet leg hermits. The blue legs I had were all killed, I presume, by the larger red and zebra hermits. Now the reds are disappearing, even though they are larger than the zebra hermits. Other tankmates are an emerald crab, porcelain crab, arrow crab, 2 peppermint shrimp, a PJ Cardinal, and a pygmy cherub angel. Various snails.
The angel is looking stressed, with some fin damage, so I believe I have an aggressor in the tank, but I can't figure out who.
