Well, I have some sad news. My little flame died during the night.
Yesterday when I got home from work, my husband informed me that she had picked out a little, out-of-the-way cave and had not moved from it since he'd been home. I watched her huddle there all evening. I knew this was bad - all day Sunday she had freely roamed among the rocks up and down the full length of the tank, picking at them like a contented little fish... Her hiding in one place with no interest in the rocks around her was very worrisome, but I didn't know what to do. I couldn't get a perfect view of her, but I couldn't see any injuries or any sign of illness other than her behavior, so I fixed some nori nearby her spot and otherwise left her alone.
In the mean time, the large flame and the coral beauty were happy and active. The CB is slowly overcoming his shyness. I saw the two of them doing some posturing that eventually ended in a brief chase (flame after the CB). This was followed several minutes later by grazing and roaming within near proximity of each other without any show of aggression.
I didn't see either of them (or anyone else) approach the little flame's cave all evening. The only signs of any aggression toward her were what I reported earlier (witnessed Sat evening/Sunday), and that didn't seem like anything intense or even bothersome to her.
I have no idea what killed her. It's possible that either the large flame or the CB decided during the day yesterday that they didn't like her after all and went after her in earnest, driving her into her little hiding place. But like I said, I saw no sign of injury, so if that happened, what actually killed her? She was eating off the rock on Sunday, so it hasn't been nearly long enough for her to starve.
She was alive at lights-out last night and dead before lights-on this morning, and from what I have seen the CB and large flame both pick beds for the night and stay there (as does the trigger), so I really doubt that one would have gone after her in the dark.
I saw everyone else this morning, and all looked fine. I did not have time to test my water this morning, but a few days ago my numbers were: Amm 0, Nitrite 0, Nitrate 5-10, Phosphate 0, SG 1.025, pH 8.1, temp 84 (I know that's warm & am working on it, but I don't think that's the problem).
I have read that these guys are very hardy unless collected or transported in an inappropriate manner - could this be cyanide? I am really at a loss.
