What kind of flatworm is this?

[PghReef]

Been having problems in the main DT so I've been closely observing everything in both my DT and my coral frag tank. Havnt had issues in the frag tank, just the DT.

Found these guys today. I see them on rocks, on the glass, on the plastic frag rack, but not on many corals just the lepto and monti. I don't see any in my DT but if they're in my frag system they could have

migrated

Looks like the common red planaria.

that's what I was thinking. Pretty harmless in that they sont "eat" coral but they can explode in numbers and irritate corals right? Maybe a wrasse for the frag tank or a mandarin will keep the numbers in check?

I have had a lot of success with Chrysiptera genus damsels. The springeri will eat them readily, my starcki also enjoys them. I've never had a problem with them other than being unsightly when they congregate and corals. They seem to gravitate to soft corals. Stay away from Salifert Flat Worm Exit. It never gets them all and requires higher and higher dosages. The resultant toxins also wreak havoc on the tank even when the directions are followed precisely.

My melanereous?? Ate all mine in less than 2 weeks. I had it bad. They still must be in my sump, but my wrasse has kept the display free.

Had one before they're great. Mine later about 6 years before he disappeared and then reappeared a month later as a zombie fish
