I have a 60 gallon planted freshwater tank. I really love the dragon-like fishes like bichirs and dragon gobies, but unfortunately they are not compatible with the kind of tank I have. The two criteria I have are:
- Won't kill all my smaller fish (neon and rummy nose tetras). If they occasionally eat one or two that's ok as long as they don't kill them all in one day.
- Won't constantly uproot all my plants. I have petco black sand. It is a pretty heavy sand, but a big fish can still dig stuff up.
