I've had in my posession a firefish for about 3 months now in a fairly established 20" cube with only 2 other small fish. He was doing great up until last week. Always out, always eating. Then for the past few days he hasn't come out of his dart hole, he also isn't eating. So this morning I tapped on the glass, and I could see his tail moving fast from the back of his dart hole. I thought he might have been trapped somehow, so I lifted up the rock and he went nuts. Swimming erraticly, moving his mouth very rapidly, and then jumped into the sandbed.
Any idea what's going on? I hate losing fish
