Organism Id help

[Galoot]

I’ve seen two of these little guys on my glass. Long, slender, flat. Approx 1/2-3/4” long. Any idea what they are? Friend or foe?

 

[Srt4eric]

No idea but it doesn't look great

 

[Mr. Seahorse]

Flatworms maybe. Foe

 

[Galoot]

I got them both and disposed of them. I’ll keep my eye out for more

 

[PjFish]

Maybe some sort of Polyclad flatworm my guess.. Glad you got it out! Had a few large leapard polys in the past that took out a bunch of my Trochus snails!! Fyi if they break in half can regrow..

 

[PjFish]

Their mainly nocturnal so check a few hours after lights out to double check

That's what I would think too. I had them in my tank years ago. Pretty hard to eradicate.

 

[Galoot]

Found another on the glass this morning. Ugh

Make that two more…

 

[Coral reefer]

Long and slender is not the shape of the polyclad ones I’ve found before.

 

[tribbitt]

I don’t think it’s a leopard polyclad. Check under corals at night with a flashlight?

 

[PjFish]

Not a leopard just said I had elephants a few years back..If there out during daylight then u may have a bunch more! check at night lights off with red light..

 

[Galoot]

My only guess is they came in on some snails I added a few weeks back. Because that’s the only thing new and I’ve never seen a single one beforehand. I guess I can only hope that the don’t prey on any thing else in the tank! Only time will tell
