I was thinking about getting a 300-320 gallon aquarium and a 900 gallon aquarium and would like to see if this mix will work for both aquariums. For the 300-320 gallon aquarium would a adult tiger oscar, adult giant bumblebee catfish/pseudopimelodus bufonius, adult ompok bimaculatus, and adult ornate pimelodus. Would that work for that size aquarium? For the 900 I would like a adult giant gourami, and adult brown bullhead catfish/ameirurus nebulous or adult vulture catfish/calophysus macropterus between these two catfish which do you guys think will be a better option with the giant gourami in the 900 gallon aquarium? Also the reason im putting adult in fronts of the fish name is because thats what stage I would put them in together. One more thing for the 300-320 gallon aquarium and the 900 gallon aquarium what fish should I put in first then last and in what order?
