whats growing on my live rock?

[kickmeqt]

I've had my tank for a good 6-8 weeks. Last night after we shut the lights off we noticed all these clear-purplish-gray slugs comming out and they were on the glass and live rock. I'm assuming this is O.K.?

Also, I have a few spots with these clearish-purple tube thingys growing off of them, as well as these 'glass green orbs' that are clustered in spots all over the rocks in little patches.

Does ANYBODY know what all of this stuff is? or have pictures to relate?

I just wanted to know from yall since you've done this alot longer. I also have 2 very happy clown fish and a snail that have been in my tank as it has cycled. and it's a 15 gal tank. Thanks!

Hi Megan,



When you say slugs.., do you mean to say clear looking bugs-like critters?

You can read more about various small critters that are commonly seen in the aquariums here, and here and also here

If it isn't that, please let us know so we can do some more guessing... ;)

As far as those orbs go, do they have a stalk/column?
It;s very hard to guess as to what the animal may be without seen it, though.

As for the small glass green orbs you're talking about, you might have what I had which is bubble algae. Take a look at my link.

This Might Be What???

This might help you out with that part of it.
