well i started cycling my fish tank about 2 weeks ago and i started using the raw shrimp. later on i bot some damsels cuz i thot they wouldnt hurt and will eventually get eaten (gunna have a pred tank) by the trigger eel or gouper. so anyways the problem i have is that there are literally millions of bubbles just floating around in the tank is this normal for the cycling process. also one of my damsels doesn't come out from behind the rocks and the other one seemed to disappear?
