I have one 60x20x20 for dorado, he is by himself. I'm sure he'll be in the pond soon. Two small 36x20x20, one for small snake heads and one as a hospital tank. One 60x30x30 for a group of Frontosa blue zaire and some others from Lake Tanganyika. One 72x30x30 for raphiodon and hydrolycus. This one is new with massive filtration system (9000 litre/hour) since these vampires need strong current. One 5.5mx2.75m pond to hold Datnoids, ATF and lots more fish, humm, I have one Red Snapper in that pond too. He's about 13-14" and has been in fresh water since he was 3", what an adaptation.piranha45 said:What size tanks you keep?
