Marius;2418658; said:Then stay away from Tropheus. Minimum 4' tank would be a 120gal 4'x2'x2' and a minimum for the colony 24.
Species: Tropheus are herbivourous species from Lake Tanganyika and they can grow ...my wild caught Duboisis are 6"+
Aquarium: As large as possible, with a minimum 4' tank of a 120gal
Substrate: aragonite, one needs the pH and alcalinity to be higher than one's average Malawi tank.
Food: preferably one brand ...exclusively, I've had good results with NLS so far.
Scape: Keep the rocks either to a minimum, you can install one of the AQUATERRA backgrounds with a couple rocks in front, or overdue it (but please research first) ...reason why, less rock=less males claiming a territory.
Colony: minimum 24, the more females the better. Reason for the number is their aggressive nature and the numbers is their defense as it disperses individual aggression within the colony.
Tankmates: I've used shell dwellers, Frontosas, Boulengerochromis Microlepis ...and I'm voting for the shell dwellers. Least impact on the all around health and behaviour of one's Tropheus colony.
Good luck
Where did you get your info? 120 gallon is NOT minumum, although it is preferred. Min colony size can EASILY be below 24, that would be like telling me that my 20 Duboisi Kigoma is to small of a colony. Also with Tropheus you can have dominant females as well as dominant males. It can be done with lots of rockwork or not lots of rockwork, both ways have been proven to work great. NLS is not the only thing to feed them, there are many options for food. As far as the tankmates I dont know that I would put any of your reccomendations with Tropheus. Microlepis get to big, Fronts get stressed by all of the craziness of the Trophs. Shellies may work but I wouldnt do it. The only fish I would consider mixing with them is Gobies.
