Guess I should introduce myself here. I have a 10 gallon and 30 gallon freshwater tank. Knew nothing the first time with the 10 gallon, so we lost the 3 fish we started... Read a little after that, and started both tanks with a fishless cycle. Currently have 3 white mountains in the 10 gallon (not sure what else to add) and 2 otos, 3 guppies, 3 plattys, 6 leopard danios, and 1 ghost shrimp in the 30 gallon.
