Okay, I have two main tanks, 1 10 gallon and 1 29 gallon. In the 10 gallon I have two platys, both female, and 3 corys. I guess that tank is pretty full so skip that. My 29 gallon has 1 african butterfly fish, 6 fruit tetras, and 1 pleco. Now the pleco Ive had since it was about 4 cm big, and now its about 4 inches big. maybe 4 1/2. Anyways, I feel like inorder for him to be happy and keep growing he should go to a better home with a bigger tank, am I right? Also, I was wondering if theres anythign else I could put in this tank because its pretty empty, that would get along with my african butterfly fish, and wouldn't eat my tetras. I had two albino cichilds for about a year buuuut one got stuck in a decoration i have in my tank (I found this out because pieces of fish were suddenly floating around my tank after not seeing him for a while ) and the other died recently (dont know why, probably sad from missing her boy ) Anyyyyways, any help would be appreciated. Also, my 10 gallon has sand, not gravel, and that was done one day last year when I had a llloooot of patience. I was thinking about making my 29 gallon sand but I dont know. Any comments at all pleeeease
