Common (and uncommon) LPS Diseases

[Twitterbait]

Lets All list some of the common ailments that effect our LPS corals and some of the cures.

I'll Start

Brown Jelly

Affects: primarily Affects frogspawn, torch and other tentacle type LPS coral but it can effect others as well. Highly contagious.

Appearance: the tissue portion of the coral bloats up and falls apart. turns the LPS head into a jelly like blob that is easily blown off with any current.

Recommended approach: Immediately use a turkey baster and suck the affected portions off, then frag the damaged portions and remove from the tank. a dip using an iodine base like lugols solution can help any remaining heads but you will need to watch for further damage over time.

Do parasites count?

Flat worms.
Treat the coral outside the tank in a bowl with flat worm exit.
Gal Crabs.
These are nasty little creatures. The female digs a hole into LPS corals while she is carrying eggs. She can be removed with tweezers and the coral dipped with an Iodine based dip to help prevent infection.
There are also bivalves that are assumed to be parasitic. They can be found attached to the coral skeletons just below the line of flesh. They will cause a deformity in the skeleton as the coral grows.

Is "brown jelly" a disease per se, or is it simply the result of a disease? If its a disease, you'd think someone would have isolated its bacterial or viral source.
