would it be overstocking if I put a comet and a black moor in a 20 gallon tank? Right now they are in a 5 and a half gallon tank but I'm planning on setting up my 20 gallon tank very soon. Right now the comet is about an inch and a half and the black moor is about an inch or so. I can post pictures if you guys need them. They are getting along fine and i will often see them swimming together. Now I know the comet will get very big so when he starts getting too big for the tank he will be going out in my 80 gallon container pond and if he outgrows that I'll move him to my Aunt's pond which is pretty big.
