It occurs to me, Lance, that you did not know that the dwarf petros are a Lake Tanganika catfish species. Sorry.
now lets see if i can get this post to make sence,
fist i hope is a photo of the tank, yes i know it is not the best around,and need a bloody good clean, and no comments on the photography please! heheh
and now the fish, there are 4 in the tank, 2 of witch seamed to have pared up and they share a shell,
the sizes of the fish are between 1.5 inch for the smallest in the tank,also happens to be the darkest in colour with the most amazing blue around the gills, to just over 2 inches for the lighter coloured one,
now i have no idea on sexes as i would asume that the darker ones are male, however i requested 1 male and 3 female, but looks like i got 3 male and a female, but all happey enough at the moment,
