your idea, i have it in mine tank 5*1.8*2 and there is heaps of room so you could, oscar,female JD,male GT, festa,female con and a random male yellow lab
really, i thought that would be a little bit too much, but i wanted to get a male jd, but if females have the same great colors as males, id like that. And i already have a gt, so thats a step in the right direction
yeah my fish are young thoe but i could see them in 125 growrn up. and i have to filters so the tank gets cycleded like atleast 9 times every hour, dont rember esac
