Right now I have the 3 females in a 29 tall, but I recently purchased a 42 gal hexagon tank for them. It will be a few days before I can transfer them over as I plan on making a naturalistic background with great stuff this weekend. I don't have a male yet...cresteds are hard to come by here in Austin so I will probably have to wait for an expo. He will probably just live with the females temporarily for breeding and then be removed as to not stress the girls out.
Thanks for the help!
