Well... I'm completely broke right now, any Rams I'd be buying would be on my moms "I Owe You" list. and I have no room for another tank. I've basically got no other choice but to use the 20long... however, there could be another option, if I was willing to scrap my plans for the 30tall (grow out for fry). If I was willing to scrap those plans I could put the pair in that tank insead.... but then I would need another grow out tank. I think Ima try my luck with the 20long first, if that doesn't work out then I can try other tanks.
