After much thought, I have decided to change my 400 from a south american cichlid tank to a tanganyikian cichlid tank. The stock list so far( growing out in another tank, until sa cichlids are gone) is 1.1 Black cap Ventralis, 1.4 Callochromis macrops, 0.3 boops(need to find a male), 10 Tropheus duboisi, 10 Tropheus moorii(musanga) and 4 Ectodus descampsi(want 10 more). I would like to add some shelly's as well as a group of Benthochromis tricoti. The tank is 96"x 30"x 30", with sump of 72"x 24"x 16"(LxWxH). I have a sand filter good up to 600 gals, a FX5 run through the closed loop holes in the bottom of the tank. I would like input as to which fish you guys and gals would add to this stock list. Thanks Jay
