I am getting a 5 gallon for my guppy fry. that is the biggest tank my mom will let me get now because im only 13 and in my room I already have a 40 gallon, 2 ten gallons, my guppy fry are currently in a 1.5 gallon, and three smaller tanks with betttas. so the only other tank she will let me get is a 5 gallon. but I am going to get a tank divider so I can put the males on one side and the females on the other. I do have a store lined up that im selling them to so i know it will be a little overstalked but it will have to do. I called petco and petsmart and the smallest size tank divider they have is for a 10 gallon. they said to check online, but im trying to but i cant seem to find a website!! can someone please give me a link to where i can buy a 5 GALLON TANK DIVIDER!!! please no comments on how a 5 gallon is too small for guppy fry. I know!! they babies will only be in there for a month or two. I am an expierienced fish keeper and have had fish my whole life!! I just need to know where I can get a 5 gallon tank divider!!
