Fish are disapearing

[papa.250]

I have had fish in my tank for a couple of years that are starting to vanish. Beside any agrressive fish is there things out there that can take down, fish. I have not bought any type of crab, not quite sure what is going on.

I have no clue why your fish may have died .. but its common for a CUC in a mature tank to make short work of a dead fish.
