thanks for the welcome everyone. all the fish are in the same tank. i dont know how i got the effect on the tank shots but i thought it looked good. its really not that bright, my camera makes it look a lot brighter. and thats a heater, not a lightsaber, lol. the 700+ tank is gonna house mainly monster cichlids, def. the baby RD. by the time i get the big tank done he'll be a lot bigger. i also want to put in some arapaima's and flowerhorns. just big guys. im a big guy, and i like big aggresive fish. again, thanks for the welcome.
