Hi, I'm going to buy myself a 400 G tank. The idea is keeping a Bimac in it. Could I keep more than one Bimac in it ? What are the difficulties in keeping multipe octos in one tank ? Thx in advance!! btw, very nice forum !! Ow, and another thing, does anyone have experience in culturing a food supply by him/her self ? Shrimps and crabs... where can I find info on that ? THANKS! Razborka.
