So yeah, I've never owned gbr but from day one (6 months now) of fish keeping I've always wanted a couple. I also want to try to breed them, sell most, and perhaps keep a couple. I'm not sure how many tanks I would need and what not...I know they need a flat stone, high temp., live or frozen food, and no aggressive fish in said tank. Also the lighting and plants yeah yeah. Sooooo, my main concern is tanks, as I'd be selling the fry to my lfs. Available tanks by the time I get my gbr, 20 gallon with cardinal tetras and sterbai corycats. A 20 gallon with no other fish in it, but cycled. And a 10 gallon with a few harlequin rasboras. Also, at what age would I sell the fry, and for how much? Is there anything that's easy to find for the fry to eat? I know they like live baby brine shrimp....but is there any other good alternative food for them? Anybody have experience breeding gbr successfully? Thanks guys.
