I've been having some problems in my 60L tank, inhabitants were: Dwarf Gourami - male Yoyo loach amano shrimp x1 Bristle nose catfish/pleco x1 Some neon tetras Some raspboras
Not long after adding them in a couple of the raspboras went missing, and then another was dead floating at the top (within the space of 1-2 weeks), I naturally assume as they're missing, they've been eaten!
Now Today we find our catfish floating with all of his insides missing.
Who is the most likely aggressor, the loach or the gourami? I know the gourami's can be territorial but they have plenty of space and whenever I'm observing he just likes to hide away. The yoyo zooms around the tank like a nutter then will rest for an amount of time after, I've never seen it interact with other fish.
