Weird Creature!!

[Shooter000]

Ok so I go into my fish room, turn on my cell phone light to check out my crazy banded trochus snail population when all of a sudden I see this flat slug thing with no head about the size of 1"by 2" flat flat and I mean flat to the rocks, and a crazy shape shifter to, as it went right into my feather dusters tube shape shifting its way in and came right back out and under a rock, me being so stunned I didn't record, am I going nuts,did I see this, any thoughts people, as I'm a little freaked out at the moment, and still wondering what I just saw:O

Ok so I just got a vid of it, just uploading to YouTube now, it's some sort of slug or something, bet it's what ate my feather duster,but I still have no clue what it really is?¿:O

Looks like a flatworm, and possibly a bad one.

He'll be happy until you catch him...

Polyclad flatworm and he is a snail and clam killer, though they also feed on many soft body worms like feather duster too.

If you have a clam give it a good look over! They will hide in the folds of the mantle.

Live rock, eegs or babies on coral.

 

[heath]

crap, how do you get rid of them...

 

[AdInfinitum]

Live rock, eegs or babies on coral.

Things like that also can lay eggs in or on snail shells so baby's don't have to hunt for food. Then the babies can live and grow for a long time inside the shell until they are large enough that they kill their "host" then become free roaming.

 

[AdInfinitum]

Eggs or spores of many types of flora and fauna will pass undigested through the guts of fish. In some cases that process is an integral part of the cycle....

This is the only one I've saw, and it's probably 4" long when moving around, haven't added any rock to the tank since the beginning, other than rock with a coral attached to it, and just seeing this one now, should of grabbed it last night when I had the chance

 

[chrisstevens]
