Can anyone give me any idea of tank sizes to keep rabbit snails and shrimp. I've wanted a shrimp only tank for a while. I was gonna get a small 50 litre tank. But my adult rabbit snail in my 125L wont stop having babies. Currently there are 5. I dont want to get rid and my 125L is well stocked. So I was thinking of getting a 60 or 80 litre to house snails and shrimp. Also what substrate is better for snails and shrimp?
