Nice forum you guys got going on here. Anyway, I have 2 40 breeders and a 20 long. I have a male convict in 1 of my 40s, and a female in my 20. A few days ago, I adopted a Jack Dempsey juvenile from Craigslist. I usually stay away from fish that will outgrow my breeder tank, but he was free! The person had him in a little 5 gallon.
