Does anyone have issues with gardneri killifish being overly aggressive? I just got a pair about a month ago and although I never see them directly picking on anyone, I've noticed that the other fish in the tank all have damaged fins, or have disappeared. I found one harlequin rasbora dead last night with the other fish picking at his corpse. So, do you think its the killifish? Otherwise in the tank there are/was Harlequin rasboras, glowlight tetras, neon tetra, and an american flag fish.

I have kept and bred many killifish, they are all bullies for the most part but Other than golden wonders I have not seen them directly kill a fish, what size tank are they in? is it planted?
