Never seen this (snail?) Before! HUGE!

[BoSalman]

So i have my tank running for almost 2.5 years now and i have never seen this one before!

Shined my cell's light at night, saw this (snail? Hopefully) about 4.5-5.5 inches long on the backwall...!

Any idea what this one is? Not even sure where it was hiding all this time!

Craziness!

Looks like a polyclad flatworm to me! I would remove it.

I was going to say that I just never seen one that big. Incredible!

Ah, you beat me to it. That's a polyclad and probably not something you want to keep around. Any issues with corals or snails disappearing?

The crazy things in our tanks are not even a speckle of what is on the ocean floor, boggles the mind

It does look big. Makes you wonder how it was hiding all this time.

Dont quote me, but this looks like a species from Cancun/Cozumel waters which grow large known as Netted Flatworm

What could it possibly be eating?
+1 on anything missing?
Lochness reefmonster was my second guess lol

I use to find large polyclads on euphyllia in the 90's, but not that large. Like 50¢ piece large.

Wow, never though i would find something like that!

Thanks you! I guess i would have to wait to see it again, that thing just disappeared again and i can't even find it!

Corals look normal. However, i did lose few trochus snails lately.. but all other inverts are fine. I'll remove it once i find that thing again!

This is exactly why i like to check my DT at night.. amazes me every night how many things we have in there totally un-noticed!

Interesting... i will def look into that, i did not expect it to be a worm for a fraction of a second tbh.. that was huge...

Lol, i stepped back when i saw that thing there.. only a few snails on the back of the rock work..

I have not added a single thing to my DT since maybe last septermber... that thing must have been hid8ng extremly well for me to miss!

Does anyone think this could be a chiton? @BoSalman is the mystery critter hard or squishy?

By the time i went to grab the net to take it out.. it was gone! But it didn't look "hard". I thought at first that this looked like a nassarius, it is somewhat similar as in thin, but length wise it was on growth! kinda has the same movement, but i never saw this before..

Can you remove the rock and give it quick rodi dip?

I will try to pin down first which rock it hid on/in.. since i saw that on the backwall.. one of the rocks has huge colonies so i hope it's the other one... turned off all the lights and its a hide and seek game now i guess...
