I have been researching tropical fish aquaria like crazy the past week. I snagged a 5 gal eclipse corner FREE and have planted it and plan to put a Betta in there. When I get more room I have a 10 gal and a 40 gal hex just WAITING for some fish. I have been keeping land hermit crabs for the past year and a half and fish seem similar but present a whole new set of complications. I kept fish as a kid of course, knowing nothing about the nitrogen cycle and listening only to the advice of pet store people. So awesome to have these forums now so I can do a better job.
