So, I am still pretty new to fishkeeping, only starting a 20 gallon 4 months ago and upgrading to a 75 gallon 2 months ago. I know I've still got tons to learn, but that being said I have been researching and getting really interested in starting to get into breeding some fish. First question I'd like to ask is, do you think I should breed in my current 75 gal tank, or buy a new breeder tank, like a 40 gallon or something like that? I'm considering a new breeder tank because my current 75 gallon is fully stocked, and I'm not sure if my current will breed a whole lot.
