Hi, I just wanted to make sure that my tank is not overstocked. There is enough room for all the fish to swim but I just wanted some expert advice. I have a 35litre biube tank, I think thats 9.5 gallons. In there I have 4 small guppies, 4 Endler guppies, 2 bumblebee catfish (tiny), 2 ghost shrimp and 6 neon tetras?
