What The?

Hi
Found some more wierd things living on my rock, would be grateful for some id's and whether possibley good or bad, some will be harder to catch than others...

I like this one.


Now this one just appeared from nowhere managed to snap it as it went round the rock ,can't see its head but the body was whiteish and it had red feeler things???



I think this is a snail


There is another snail in there with the same size and shaped shell but its patterned like the sundial snail???

And damn those sea hare's grow fast,how big do they get exactly?

 

Hard to tell, but I think the first one is a FD, the 2nd might be a sponge and the last one is definately a snail. Luna

 

2nd One is a creepy crawly worm of some sort?

 

The little snail is an Engina species, either Engina carolinae or Engina zonalis. They are predators, but shouldn't be much of a problem in a reef tank. They will most likely eat worms and small vermetids, and maybe other tiny animals. Same family as the "Bumblebee Snails" that the suppliers all sell.

Engina carolinae

Engina zonalis

Cheers,
