+1, but i did have a male blue turq discus, that was so funny, he would try and attack the office chair, every time it rolled past he would go nuts, and i ofcourse took avantage of him, testing the wheels on the chair :lol: :slfg: :rotf:
buy some flourish excel, and put the rock in a bucket ( just big enough to fit the rock) then fill with hot water and double or even triple dose the thing with flourish, (the algae should start turning red after a 1-3hr hours?)then give it a scrub and a wash in another hot bucket of water. thats how i do it
