Had a lady bring in 45 Platties, that averaged at least 1.5 inches each, 2 Cory Cats that were 2+inches long each, and 2 Pleco's that were between 4-7 inches long... They had all been in a 20 gallon tank, and it had not been cleaned in 4 years.... I almost went ballistic on her, and wanted to tell her that if she did not want to take care of her fish, then she did not need to get them in the first place.... But, they are slowly finding new homes with people who care...
Oh, and she started out with 8 fish... I would like to meet the person who sold her the fish, and told her it was alright to put 8 fish, many of which breed like crazy, in a 20 gallon, and that she would never have to do any water changes.
