hi everyone i'm looking for some fish that can breed in a 20-30g tank that i could actually make some money on. i have 3 other 20's i can use to grow out and could probably get a 55 or more 20's or a 30 or two my. i'll use the money to get my +240. i was thinking about keyhole cichlids but it doesn't look like i could really profit of them. thanks for the advice.
