Another good point. At one point or another "the common" fish was hard to get, exotic, and expensive. We have come to a point where most of the FW fish that has been discovered is in the aquarium trade in one form or another. Im sure, the more exotic fish will be bred easier and become less expensive and be refered to as "common" this will take MANY MANY YEARS to accomplish and many fish that are exotic cannot be mass produced. Since there is not that many new fish entering the fish trade, we are "making" are new fish: AKA flowerhorns and glow in the dark fish. Is this good or bad? Who knows.. But a 60 gallon tank full of Glow in the Dark fish must look REALLY KEWL!
