Well that's a bummer so does anybody know how many mollys, platys, tetras or guppies I could put in a 20 long? We were up in the air to which we were going to do. I already have the 20 gallon I had a couple cichlids in it but I just recently got a 55 gallon for them for my b-day so now I am restocking the 20 gal and haven't decided what I am going to do yet. Thanks for all the help
