I have a 20" long giant gourami in a 70 gallon tank. Powerheads on undergravel - H.O.T. magnum and a Rena Filstar running underneath. Any obvious changes that are not too expensive that would help for general fish health? It is a 30 year old Osphrenymus Goramy? I think (don't know male or female) so must not do too bad, but am open to improvements, and positive ID for this fish!
