I have been told that my tank is overstocked. I have a siamese algae eater, three snails (not sure what kind), two african dwarf frogs (one male, one female) and a baby betta (about 6 weeks old) in a 2.5 gallon tank. I'm just wondering about the consequences of overstocking your tank. All of my animals get along well now that they are familiar with each other. I have no problems with feedings, and they seem to be on different levels of the tank. What is the worst thing that could happen if I keep them so densely populated? I have a ten gallon I could move them to but I doubt that my mom would go for that.
