I think David and Brett basically summed up any contribution I could make. The only other thing I've noted with them is females tend to be avid burrowers if given a chance, and will give preference to an excavated cave under a bit of wood, rather than a pot. Therefore, rather than using pots you might try a bit of bogwood (or alike - boiled first) on an inch bed of sand. Oh yes, make sure that the wood is supported off the tank floor with something of substance - squished fish are not a nice sight. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
