dont be so lazy and get off your a$$ and clean your tank. Then the will not get fin rot etc... if yoiu cant look after them you shouldnt have any fish... :angry:
Just scoop it out with a net and then put in the new sand first. it wont need washed or anything as your filter will clean it for you anyway. I done that with my 4 discus and it worked a treat.
450 and i didnt edit that bit. & just because you have 5 fishes above your name doesnt mean u run the show.
