Hard time identifying. HELP!!!

[TwistedCourtea]

Found these little critters today. They move kind of like a snail or slug. Some are reddish and some are dark, On my glass and rock.

Looks like a flat worm unfortunately.

maybe red planaria?

Look up acoel flatworms.

Look up acoel flatworms.

I agree that it is a species of Acoelomorpha, as for specific species it's very hard to identify without the right books (which I currently lack). most species are detritivores but some have strong antipredator defences making them populate quite rapidly. also a couple species (definitely a minority) live on corals either as commensals or parasites

Look up acoel flatworms.

I agree that's what it is. Thankfully this is a pretty much empty 5 gallon tank with just some rock, a snail, a hermit and a small xenia frag and not my 24 gallon main tank. Getting rid of them shouldn't be too hard. Thanks!
