Forgive me in advance if this is a stupid question. I saw a 40 breeder in person for the first time today and I noticed that the tank is just as deep as a 75 gallon. So my question is, why can't I just keep my single flowerhorn in a 40 gallon breeder? Is seems like the main reason he will out grow my 60 gallon is because it is only 12 inches deep. Even though the 40 B would be shorter in length, I would still like your opinion on how he would do in a 40 B permanently.
