Hello, I have a 55 gallon tank (48 inches long, 12 inches wide, 24 inches tall. Not 100% sure about these dimensions and I'm not home) and I was wondering what I should stock? This is what I have so far: x8-9 zebra danios x8-9 bloodfin tetras x? Cory catfish I don't know how many corys to get. If you have any other ideas, additions, subtractons, completely different stocking ideas, I'm all ears.
