Question for a newB

[gregr]

I am new to the saltwater world. I have little white flea like critters running around and I have black and skin color looks like little slugs. The little flea like critters are about 1/2 centemeter and the sluggy things range from almost invisible to about 1 1/2 centameters long. Any ideas on what they are and if they are good for the tank

WELCOME TO THE BOARD!!

The little flea things are probably pods... tiny little crustaceans... very beneficial.
The slugs could be some sort of nudibranch (possibly good)... or flatworms (bad). Really hard to make a positive ID without a better description or pic.

they are not flat the look like slugs they have two antenna's and they have a smooth bottom and their bodies look like a land slugs.
Thanks for the welcome and info

The "slugs" are probably nudibranches, from your description. I don't have a clue as to what type of nudi they might be though.
