My flagfish started eating algae almost immediately after going into my 29 gallon tank, but they soon discovered something they liked better--ghost shrimp.
It started by their taking my puffer's krill, and escalated from there. They got a hold of a ghost shrimp that was either dying or moulting and tore him apart. Every day we've noticed fewer and fewer ghost shrimp in the tank, and now we're down to one. Just a few minutes ago, I watched them eating what was left of another.
Mind you, aside from the first one, all the other shrimp seemed healthy. And we're not talking SMALL ones, here! These are those super jumbo guys that my puffer wouldn't eat because they were too big. They've been in my tank for 6-8 months with the puffer.
Then this morning, I found a dead oto that had been partially eaten. I suspect he died first, as he wasn't looking too good, but this is getting crazy.
I understand that most fish are opportunistic omnivores, but I think this behavior is going beyond that. They seem like flat out carnivores!
I'm concerned for the safety of my puffer at this point! And to think I was worried HE would hurt THEM...
Has anyone else experienced this with Florida Flagfish? I had read they could be aggressive so I bought two females. I certainly wasn't expecting this!
