I would set up a tank of 80*40*30 cm (96 liters ) to kep Nanochromis transvestitus. My questions are : 0 is the size of the tank enough for this fish ? 1 the soil : sand or little gravel ( les than 2 mm ) ? 2 the filtration : if gravel is good , what about UGF? 3 heating : under the soil or normal ? 4 how many fishes : a couple or a male and two females or 2 couples ? 4 others inhabitants : I think that's good to have 5 Nannostomus beckfordi for the upper level of the tank and I hesitate to add up Nematobrycon palmeri or a couple Pelvicachromis taeniatus for exemple. What do you mean about this ? Many thanks for replays and advices J.Besson PPS Sorry for all this question although I've seen the archives of the thekrib on nannochromis tranvestitus ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
