Found this creature, slithering around the tank today. Hard to get a good picture as it's brown/dark red, similar to the rocks. It's got 4 antennae on it's head. Kind of a blob, but can stretch out to get from one rock to the next. Doesn't seem to hurting anything. Brushed up against some SPS and Zoa's and didn't seem to have an effect. Seems to be looking for food. I guess a nudibranch of some sort.

First picture shows it stretching between 2 stags. Next picture, you can see its head right in the middle of the pic.

Looks like some type of sea hare

Thanks Wiz. Interesting how it came out of nowhere. Haven't added any LR for over a year.

Np. Its entirely possable for them to live there entire live in a porous rock. But if you don't have a huge population you might not see them anyway.

Ok, I know most are not as interrested in thy tiny sandbed fauna as I. But Im having trouble with this one. So I figured it didn't hurt to ask. I can usually find my answers through google. I've searched this one for two days and can't find it. There are two seperate vids of this worm. The first was taken on 8-7-15. The second 8-11-15. Strange because the worm is definitly the same one in the same place and moves exactly the same but it looks completely different 4 days apart. Any help would be appreciated. I assure you I look these tiny guys up often and it is not your usual subjects. I.e. bristle, penut, fire, spaghetti.

Ok. I know this is a Bivalvia. But uncertain if it is a clam, scallop or a mullusk. I have a few pics, hope it helps. Tried to make them really clean. Two types that have really started to grow and produce coloration in last 6-8 weeks

Amidst some paly

This is almost the same, but this one has a really nice purplish coloration.

To me, one looks like a clam and the other one a mullusk. But I'm not certain.

Both look like mussels to me

Ok. Any special concerns or care requirements other than feeding for filter feeders?

I have one of those imbedded in a zoa colony; I've done nothing specific and figured it would die off at some point; that was 2 years ago and it is still alive and well!

Mine are both the same. Never realized I had it till a few months ago. Cool creature and good filter feeder, I'm sure it helps contribute to a cleaner system in some regards, right

I need help confirming ID on these two hitchhikers. I'm thinking the one on the Glass in a Stomatella while the one on the rock on not sure between an abalone or Stomatella since it's pretty small.
