I just bought a 60 gallon tank last week and I was wondering if I would be able to add a couple rainbow cichlids to the tank. I currently have the following in the tank:
2 angelfish (small)
4 neon tetras
Definitely not. I think the rainbows would kill the guppies, corys, and tetras. I also think your angelfish (when fully grown) will eat the neon tetras, they are not a good pair sadly. I also have a concern that the cichlids would nip at the plecos eyes. Cichlids are beautiful but evil creatures.
