Check on the glass. Mostly at night with a light. If you have predators in your tank like the wrasse you mentioned, it may be holding down the population.
This is comforting lol. Sounds like I should move my wrasse here for a minute and see how he does or get one from the fish store.
Whew, thanks. I might get a wrasse to see what happens. Do any inverts eat them?
It'll really depend on the species. There are more experts in flatworms on here that hopefully chime in and can give an exact species identification. Some flatworms are more toxic/noxious than others, and that limits what eats them. For example red planaria is a real plague in the hobby because it reproduces quickly and is incredibly unpleasant to eat so most creatures don't touch it. Things like cleaner shrimp of most varieties (peppermint, skunk, fire red) will often eat some of the "tastier" flatworm species
So I have a TON of these crawling on the glass of my QT tank. I also have tons of pods and confirm these do not look or move the same. The pods have tiny legs and dart around. These move like a slug/worm and have a different shape. They head in the direction of the rounded end and the two peaks are in the rear. Any ideas?? They are about the size of a larger side pod.
The only way these can harm coral is in the unlikely event that they become so numerous that they cover the coral and "smother" it from the light.
