I'm noticing in my tank alot of tiny parisites that crawl all over the tank. They also are on my clams and snails. Are they bad for the tank? There are so many of them and hard to see unless you look very closely.
I have a 25 gallon tank with 13 lbs. of live rock. I want to keep corals. Do I need more live rock? I do not want to put too much because i plan to get fish and I do not want my tank crowded.
Thanks for any help.
