Alright, thank you! I don't have the tank or the fish yet and it's still kind of a toss up between a 55 and a 75 gallon. Would a 75 gallon be able to support another dojo loach?Kribensis27 said:You could probably only go with 2. They produce a lot of waste and more than 2 could overload the tank. For tank mates, I find that larger livebearers such as mollies, platies, and swordtails work well. Platies don’t get very big, but I’ve seen mollies and swordtails especially reach 5 inches in length. You could also maybe do a paradise gourami, as they like cooler water, but I would only do one as more than one will fight.
