Like the gallery moderator asked me to put my pics together I put them togehter in one single image (may take a little time to download). So you can take off all the other ones.
Fish are malawis (mostly predators) which live in sandzones in the lake malawi. T.Macrostoma, T.Maculiceps, N.Livingstoni, T.Nigriventer, A.Christyi, C.Caeruleus, P.Milomo, C.Moori, F.Rostratus, N.Fusco, P.Phenochilus Tanzania and 3 Synodontis Multipunctatus.
Dimensions are 250cm x 80cm(height) x 100cm(depth). Filtration works with 12000 litres per hour (2 pumps) out of a 400 litres filter tank under the main tank.
I regulary have to give fish away because they breed every week since several months.
So I think they can't be very unhappy.
