Poor little Fishy…
I have the worst luck with pet fish. We have had several! The latest fish to go was a cute/ugly little Black Moor with bug eyes. He was in the tank with 2 other fancy fish, and they were all doing so well, or so I thought. Before going to bed the other night, I went to feed them and noticed the black fish was completely missing one eye! I suspect that the bigger fish attacked him because he seems aggressive towards the smaller ones.
I think perhaps the little one was sick and may have been too small to be in that particular tank with those larger fish. The nitrate level, etc. might have been too much so he was not well, and the fat fish took advantage of him. Poor fishy. 
I was not sure what to do, so I read up yesterday, hit the pet store after work and got Melafix and water testing strips. I asked if I should move the sick fish to his own tank, etc. and I was told that the move might be too stressful, so I left him and medicated the whole tank.
Well, he did not make it. I found him floating this morning.
I am not sure what I will tell the kids yet. We have already gone through a few different fish (Betta’s).
