I'm very undecided and need your help in choosing what to do with my 47 gallon tank, that's 30" high. I currently have a community tank but I'm very unhappy with it and want to change it. I initially thought I'd try salt water but I"m not sure the tank is big enough. Then I thought about an African Rift Lake Cichlid tank, but in reading, they get big. I also thought about a figure 8 puffer tank. I think the best fish for tall tanks are discus but I already have a discus tank. This tank is sitting in my living room in a perfect spot so I can't get a larger tank. Any suggestions as to what would be best suited? :help:
