The more I read the more confused I get. I am making a list of fish I want for my 75 g once it cycles, and the specter of overstocking it looms large. I would like a group of clown loaches, which can get to be 12'' long each, but can I have other fish in there too? It seems to me once the clown loaches hit their mature size there wouldn't be any room left ("room" as in good water parameters) for any other fish. I would like to have a selection of rainbow, zebra danios, tetras, platies, hatchet fish and blue dwarf gourami, if possible. I'm used to small tanks with small fish so the thought of stocking this 75g has my mind reeling. Help!
