weird blue slug thing

[jesse]

it was on one of my coral and it is blue and looks like it has feathers on it. it looks to me like a slug of some sort? is it good? or bad?

Nudibranch. Google them to find out what he is. Some are good, some are bad.

It almost looks like a blue sea lettuce nudibranch....if so, they're good guys.

and i found another slug thing but this one is brown and just looks like a tiny slug..... where could all these slugs come from?

There are literally hundreds of different sea slugs, which all have different requirements, that it could drive you crazy trying to identify it. There is a site called seaslugforum.com that has names, pics, and requirements of hundred of nudibranchs, but for now until you can id it, maybe place it in your fuge/sump, or in a small jar with holes in it and leave it in the tank. It could have hitchhiked on some live rock, a piece of coral, or some micro algae.
