More of my wierd critters! ID?

This morning when I turned the lights on, the red slug/nudi thing was out and about so I got his picture! Or maybe it's a her. It left another pink ribbon spiral at the top of the tank this time. Here it is:

and here is my new toy I got yesterday!



Old Sump with poopy mccrappy 5 year old skimmer:


Beautiful New Sump with a skimmer that actually works!!!!


Also, I didn't bother with a picture, since it wouldn't show much, but there is a wierd line in my sand that moves. Whaddya think that would be? It's probably about 3" that I can see anyway. Not moving fast, just changing position ever so often, enough that I noticed it. It's like a spot in the sand where there's a little skinny ridge that sticks up a bit and changes position periodically.

SOOOO excited about my new skimmer! The one that came with the tank was old school. It was open at the bottom and most of the time the bubbles just kept coming out the bottom instead of making foam at the top and I was constantly having to move it around to try to find the perfect position to keep it working and it would move itself back so the pump suctioned itself to the wall of the sump and would quit working at all and if I got it right and it worked for a while, you could look at it wrong and it'd stop again. Very frustrating! So the new one is quite an improvement! May not be the best of the best, but if it works consistently, I'm happy. :grinyes:

Thanks!

hmmm, it looks more like something is sortof on top of the sand, but has sand all over it, it doesn't look like a "dune". LOL

So far, I haven't seen the nudi even out anywhere near corals - ie, on top of rocks. It stays hidden during the day. Once I turned the lights on, it made it's way to the bottom and around to the back of a rock and flattened itself down on the rock so it almost looks like a sponge or just a red/orange piece of the rock.
It's SO neat looking. I hope I don't have to take it out. It is SO much fun finding all these different things in the tank. Last night with my flashlight, I found some sort of little bitty crab hiding out in a hole in the main tank and another one down in the fuge on one of the rocks I put down there!

Yes, that's it! Thank you! Those are okay guys, right? It's getting creepy how many new oddities I'm finding since getting my TBS rocks! Fun creepy though. ;-)
