I might end up kicking myself later but I just added a decent sized coral to my tank w/o dipping or QT. First time I didn't buy a frag.
My QT has a new fish in it right now and I will start to use products to get rid of parasites, so the coral couldn't go in there.
The reason why I didn't dip is b/c the coral came w/a coral crab in it. I noticed it while acclimating to tank params. To save the crab, I didn't dip. The coral came on a piece of rock, so who knows what is inside it. There was a orange sponge, red sponge, and forams on the outside of the rock. Unfortunately there also was some green and red hairy algae, which I took a toothbrush to before it went in the tank.
