Look to large to be Planaria. Probably Fluke Worms like you stated.At my LFS I noticed these worms all over one of the tanks. Are they fluke worms?

Looks like large planaria to me...
Yeah, they can reach quite large sizes... i’ve had large ones like that in my planted tank before and are a real PITA to get rid of...Never knew they got that large.
They get quite annoying at that large a size as the buggers can move around quite quickly and are impossible to kill without meds...Eww, interesting never seen anything like it. Looks like maggots.
True. I kept my eye on one when saw for the first time in my tank and tried to caught but no use. It vanished into substrate.They get quite annoying at that large a size as the buggers can move around quite quickly and are impossible to kill without meds...
Yup they're in the shrimp tank. I will talk to the owner.Definitely planaria. Not too concerning if your lfs having fish in that tank but they are a big killer if the tank has shrimps. They wiped out my extremely expensive taiwan bees colony in no time. They grow very fast as well and they can be very big. Your lfs need to take it very seriously or else he may have planaria infestation in his store if one of them goes to other tanks with nets or something. There are many ways to kill planaria. Medicines available which are shrimp safe.
