What is this? Good or bad? Saw this at night.

Hey everyone,

I'm 6 months into my saltwater aquarium. I woke up in the middle of the night and saw these two. One looks like a slug and the other is a snail? Can you take a look and let me know if these are good or bad for my tank?

Possible slug or worm:

My guess would be neutral.

RWEngineer · 10/27/2015, 06:21 AM

How can you tell?

Ron Reefman · 10/27/2015, 06:23 AM

It blends in with the background so well I really can't even see it!

Sk8r · 10/27/2015, 10:04 AM

1 is probably a nudibranch. They can be a problem for soft corals. 2 could be a stomatella snail (has a saddle instead of a full shell and is quite desirable.)

Shawn O · 10/27/2015, 11:42 AM

Sk8r, I don't see 1 or 2.

Dkuhlmann · 10/27/2015, 12:23 PM

I don't see the first ones as well

I see no pics at all.

Yeah, this was a joke because I don't see any pics either!
