Ok this is going to sound odd and I am very new to the hooby so apologies if this is really silly but a fish has just disappeared from the tank. I have checked the filter etc and can't see any remains of it having been swallowed up ala "Finding Nemo" but I have checked the tank thoroughly and cannot see any trace of the fish or its remains.
Could it have been eaten by one of the other fish?
