I'm looking into my tank, and I noticed there ALOT of tiny species walking on the glass, I didn't have these in my old tank?? Anyone knows what are those?
Copepods, suck them out and grow them out in a little container like brine shrimp, give em tiny bit of flake food, and they will multiply, then feed to corals.
woow... sounds like they are good.. But then how do you suck them out from the tank? Do they need water flow in the container? Will I keep them when I clear my glass with the magnet?
