I have 16 neon tetras, 7 zebra danios, 3 cherry barbs and 3 serpae tetras in a 20 gallon long. I'm seeing nipped fins on all of the fish. Who's the culprit? I also had some red eye tetras in the 20 gallon but took them out as soon as I saw them fin nipping. I think they were responsible for some of the fin nipping but who else could be responsible?
