I'm setting up a 75 gallon and am still thinking of stocking options, but lately while looking at different fish care I've noticed how many fish are very difficult to breed, which I assume means majority of the fish purchased would be wild caught. The thought of fish being taken from their natural environment and put into a small glass box bums me out a lot. Anyway what kind of fish do you guys know that are almost definitely captive bred? I've had a bunch of tanks with little dudes and schoolers, this time I'd like to try out some bigger guys. Any suggestions?
