Had two of them in the tank so far that I've seen sucked them both out don't care if good or bad haha not taking a chance. Never noticed them till I just put a new cleaner shrimp in the tank from lfs the other day then noticed two of them one the first night then this one the second day

Not sure that one look big. Does look like an Acoel flatworm or possibly a ghost flatworm. not sure will let other more experienced answer for sure.

Yea I looked all around and everybody seems to talk about the reddish orange ones being bad but idk saw two of these and took them out instantly haha and yea they're were about a cerith snail with the shell size. Honestly they were pretty cool to watch move in the tank. But wasn't chancing anything.

It took me three weeks of siphoning out flatworms every time I looked at my tank to get them taken care of. I have not seen any in the last two days. I would get 5-10 every time I looked but they were mainly on the glass not the rocks. If it is the Acoel or ghost then they are after the algae but they are a nuisance more than a coral eating problem, but I would get rid of them ASAP. How do you think you got them?

I am thinking mine came in on snails that I purchased online but not sure.

Best I could find is some Amphiscolops sp. always best to remove.

Yea honestly I've only seen those two and that was two days ago, I work from home with my tank right in my office space so I'm always looking at my tank like all day hahah haven't seen anymore yet. But I purchased a skunk cleaner shrimp the other day from lfs and saw the first one the night I put it in and the one in the pic the next morning so I'm assuming came in on the shrimp. Funny too cause it molted the first night It was in my tank and the molt was stuck to the wave maker the next day thought the shrimp was toast
