I alwys give to pieces of algea sheet in my tank one on one side with a clip and another on the other side. Sometimes my fish punk my Sailfin and dont let him eat so i do this that way he can grub also. I try and add the sheets before lights on because i have a Flame Angel that loves to pick on my Wellsophylia if it does not have Nori to pick on. this past weekend i was reallt bussy and was getting the sheets in really late and my brain was deflated and i know it was becasue of the tham flame angel. Now since monday im back to my routine and everything is good again. Im almost at the point where i want to remove the flame but i love his colors. So i know what you going thru, hopefully your kole recovers.
