I have a 29 gallon aquarium with 8 Harlequin Rasboras, 2 German Blue Rams, and 3 Corydoras. I know that Rainbow Sharks are a little less aggressive than red tailed black sharks, so would it be possible to add them to this community tank?
Yes you can, although you can only house one of them, they are very aggresive to there own kind. They get to be about 5.5" long, so your tank is big enough. Try checking out the albino, I had one of those about 2 years ago.
