Found this monster in my tank last night

WOW! Very cool, beautiful Nudibranch and see if I can find and give you a positive ID in a few.

Cheers, Todd

Thanks it's had to be in the tank for a better part of a year hasn't seemed to bother anything but I don't want to take any risks

 

[TJ's Reef]

Still looking for you.... What have you introduced lately if anything ie; new LR or big Soft Coral attached to LR ??? Sea Slugs are normally quite specific feeders and their coloring and or patterns often give a good clue to what its preferred diet is.

Cheers, Todd

In the past year this hammer and these chalices are the only things I've added

 

[TJ's Reef]

Drawing a blank finding it in any of my many books but the link below will get you an ID I'm quite sure. I linked directly to their ID page so just post same pics and see what the real Sea Slug Pros come up with here. I've spent nearly two hours wandering around in this vast forum on Sea Slugs and related species, very impressive.

Pretty sure that is a polyclad flatworm. Def not reef safe too

Here's a link

That's a polyclad flatworm, bad news. They are carnivores - snail/clam predators.

 

[GHill762]

yep flatworm.. a decently big one too.. they are definitely neat, but not good for your reef..

 

[ellyons]

I'm glade I pulled it out surprised it didn't bother my clam

Can someone help identify. I found these In my HOB filter. Please help.

Looks like they may be feather duster worms to me - if so, they’re harmless filter feeders.
