Has anyone come across a dwarf type of occie? I have 7 occies of which 2 are female. 3 are very large males each just over 2" TL and 0.5" deep in body. One of the other males has an all-over golden colour, like the Zambian morph shown in the Aqualex, but he is no more than an inch. So is this Zambian morph also much smaller?
