i can't really say i know much about them. they never seem to have them around here. i do know that they need a low PH, but thats all i can tell ya, sorry...
hmm... could the chocolate gourami be the females dwarfs?
i didnt check the links and couldnt see a pic, but i heard the males are colorful and the females brown. my lfs wont even sell females b/c they dont sell due to lack of coloration. i want a female dwarf though!
