Thanks, yeah a 30 gal would be awsome, brevis are cool, maybe if i had my time back id go occy's though.
Potts050, yeah if i leave the fry in there they'd get eaten, but im just going to remove the shell and fry, grow em out for a bit and then put em back in. I recon the calvus whould have a hard job even getting close to the sheel with the male brevis though.
