Ya garlic extreme , I use what the directions say. Ill probly get some pics of the sharks up soon. The lemon is not growing in length but in thickness , the built bulky look of lemons. Bamboos are good and getting large. In a about three weeks i am getting an upgrade, a tub for the sharks. Has anyone ever breed yellow rays. im going to try to. I know that they mate in the spring but thats it. I might get another larger female cuz I dont want all the stress on one female if they do mate.
