So my mother bought a 10 gallon fish tank a few months back. We quickly bought 4 glofish and a snail my son named them after characters from his fav tv show. Problem is he wants another glofish, I know typically glofish can grow to about 2in so in theory we could have 5. However we have the snail and I'm wondering if that means we can't have anymore. Please help me I know he would be thrilled for "Teacher Sussie" to join her students. And before you ask I have no clue what kind of snail Turbo is (yes I know original) and my tablet isn't letting me upload the picture. He is white and bigger then the fish. thanks!
