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

 

[Galoot]

Just an update, Since catching and disposing of the four I found, I have not seen any others, day or night. Fingers crossed I'm good!

You’ll never see them all
Wrasses will help

Agreed! I’d like some wrasses, but they will also crush my snail population, right?

No
Feed your fish more

 

[Kensington Reefer]

@Galoot
Not to side track, but...
What do you feed your fish.
How often?

 

[Galoot]

Frozen foods of different varieties, mysis, brine, mixed meats, etc… TDO pellets, flakes, nori

 

[Kensington Reefer]

I like the Rod’s and LRS feeds too
No one feed meets all nutritional needs
But if you feed a varied diet several times per day
Your snails will thank you
Your fish will too

Probably like roaches. If you see one, then there are a bunch more that you probably can’t see. If it’s bugging you, try flatworm exit.
