It's got the baby flower horn in it now. He was in only a ten. I'm going to try to get him in better shape, and move him to my 30, then maybe in future, upgrade again.
then, that 20 will be housing two baby FH that he bought with the aro, and when they're bigger, I'm going to use the same methods you guys suggested, but I will probably only take one out so he/she can have the tank all to him/herself.
