Help!! I have a 29 Gallon planted aquarium that is several years old. Initially we had zebra danios, cory cats and platies in our tank, and with the offspring of the platies, they kept us busy for a few years. Now, we have only 3 zebra danios and 2 cory cats remaining. I wanted to try some new types of fish this time around. I went to my usual local petstore two days ago and was saddened to discover my usual "fish guy" who never steered me wrong was no longer working there. However, I followed the advice of the girl who seemed to generally know what she was talking about. I purchased 3 male dwarf gouramis and 6 serpae tetras. The problem is, all three of the gouramis are having their fins nipped. They don't seem to be going after each other and, in fact, seem to have a very peaceful temperament (now mostly hiding!) I suspect the serpae tetras are the culprits though I do also have one zebra danio that is kind of a bully. So what do I do now? I called the petstore who said I could return any of the fish. I do love the look and grace of the gouramis so I'd love to keep them. Will their fins regrow? And what would be a better pairing of fish for this aquarium. Thanks in advance for your advice.
