I had an octo about 6 months ago. He was a pet at my work and im in charge of keeping the tank up. Well the octo died a while back and we put a stars and stripe puffer in the tank after his death. now everyone wants and octo again........Is that even an idea to be thought about? Lastly these white critter that used to be all over the back tank glass are everywhere in the tank. they dont seem to be buggin anything but do any of you know what they might be. they look like little white worms a 1/8 of an inch long.
