thanks
Thanks severum mama. The 2 bolivian rams do hang out more at the bottom. I've got lots of cover, but they mainly like hiding under a piece of "curio" (?) wood that I have in there. This wood makes the tank water a little bit brown, and probably lowers the pH a little, which I'm sure the rams would appreciate. I watched them feeding this morning and they just picked their way across the bottom, snatching up a piece or two whenever they saw it.
Do these Bolivian rams live much longer than blue rams? I think someone posted the other day that they live 3 years or more. The two I've got are not quite grown, but they are already larger than most blue rams I've seen.
