Yet more problems/bad critters

[Fly Guy]

So i have added so many corals to my systems in the last year and unfortunately havent been following a quarantine program.

That practice is no longer. Regardless, i just dealt with the LRB issue and now i have something else eating some of my hard corals. I had a large tort colony and a couple of pocilapora(sp) frags that i last night tried to save by cutting off the good parts, sealing anything open with crazy glue and mounting them on new rocks.

I dont know what did it. I have been staring at corals for days now and my eyes are playing tricks on me. I did notice a few flatworms around the base of the tort and the poci had these tiny white clearish things covering a few polyps...when i removed them, there was nothing but bare skeleton remaining where the thing was. I have also seen this same thing on a couple of montis.

How small are, and what do those little white nudibranches i have heard about look like?


Can a few flatworms be the demise of a fist size colony or were they simply being opportunistic?

Im breaking down the tank in question this week so i plan on using salifert flatworm exit right before doing so. That way i wont have to worry about pollution so much.

Input to anything above anyone??

That sucks to hear man. If the flatworms do in fact eat the polyps then it wouldn't take too many of them to do damage. i would look at doing a dip on all the coral before moving it over for sure.

What disease or pest can eat and/or destroy a colony from the inside out or underneath where its encrusted??

Do you have any hairy acro crabs? I just pulled two from my tank and all my dead spots grew back in. Good luck!

What is a hairy acro crab??? If theyre very big im pretty sure I dont have them. Want to know more though......im looking for anything. The only water parameters that arent good are i have been having some heat issues and going from 78-82 daily. Also i tested my magnesium for the first time and it was under 1000. Im using reef crystals and have been doing lots of water changes due to the LRB's. Magnesium is ordered and ive been advised to raise it very slowly...like 100 a week. Input anyone??

I am also curious exactly what those little white nudibranch look like htat ive heard eat some sps and what the symptoms of their damage is.

Yeah...ive got both on different corals. Id kinda like to identify whats going on a little more precise than those catch all acronyms though. Ive fragged up two large colonies......with what seems like about a 80% success ratio of the pieces fragged, which i guess is a ok success rate considering the colonies were headed for demise as they were.
