Ugly slug like creature?

[JordanB]

Hi everyone

Found this guy crawling around on one of my rocks tonight. Im not sure if its a slug or flat worm. It has really grown over the past few weeks but tonight he was on a rock I could easliy pull out of the tank. The first two pictures are what he looked like a couple of weeks ago.

Just wondering if it is safe to keep or should I dispose of him?


Fyi, my tank is an an 80gal. has about 90lbs of liverock, 1 yellow tang, 2 pajama cardinals and 1 clown.

Thanks
Jordan

Hi Jordan B ; Welcome to Reefland and I have never seen such an ugly slug. Are you going to keep it in your tan?.Happy Reefing!!!!!!!!!!!!!!!!!!!!

Extremely ugly is an understatment. I removed him as I didn't want any problems plus he was getting a wee bit big.

or a flavor of stomatella...neither of which is harmful...they are great grazers
