Hello iam new here, I have a 100 gal. & a 30 brackish tank. In my 100 i have 8 target fish- every one else moved out! When i got them all i could find out was thay got 6 inches. Wrong has to be. I have had them since march and they are already 5 inches! I feed them frozen krill and frozen blood worms. I would like to know how big they get and what i can feed them. They don't eat off the top or bottem of tank. Thanks for any information you can give me.
