Pix & ID: Critters that come in your rocks: the good and the bad.

Close up and snail pics aren't showing for me (1st & last).
Not sure what kind of ID you're looking for on the bivalve, there aren't many that have common names so usually you just get "it's a bivalve" LOL.
 
currently cycling the tank atm and i find this

Ideas anyone
 
Aptasia

Aptasia

I unfortunately found my 1st aptasia this morning. I have looked high and low for others, but found none. I'm assuming from reading I should hit it with some Kalk paste?

Also noticed some greenish polyps growing in some of red turf algae. Kinda hard to get a picture as in back of red cap montipora. Assuming they are bad and should be exhumed as well? Or leave alone?

Tank is 9 months old and mixed reef tank, 90 gal bowfront.

Not sure what the greenish polyps may be, perhaps hydroids. I've had some that had a greenish tint to them before. Do they look like this?

So, I have had my tank set up since last September. A few months ago, i noticed this odd bubble thing attached to one of my live rocks. It its smooth and soft to the touch. It is white and purple in color and appears to be a filter feeder. Does anyone know what it is?
Thanks,
Kyleen

Ok, sorry, no pic right now. Apparently the smart phone app doesn't allow for pic uploads

Clam or Oyster?

Clam or Oyster?

Hi There. Does anyone know what this is. It was advertised as "Purple and green mushrooms on rock" from LADD. I noticed last week that the rock wasn't a rock.

There's definitely tissue inside and it reacts to light (more tightly closed under bright light).

Thank you. That's what I figured. I was a bit surprised when I discovered it. Do you know if it has any specific requirements? Should it be propped up (as it is currently) or placed on the substrate? It get's a fair bit of indirect current where it is.
 
Hi guys. Just to be sure, these guys are good worms?
I'm thinking they are bristle worms, but I haven't seen any red bristle worm pictures.

You also have aiptasia on that rock.

johnc99, I don't think it matters much how it's placed as long as it gets some of that current so it can siphon food out of the water.
 
Found what looks to be a small (~1cm) black stomatella with a fairly symmetrical oval shaped white shell. Any ideas what it might be?

Also, I've found a number of anenomes a bit too small to photograph. Generic brown zoox color, roughly 15 tentacles with white tips (but not balls). The tentacles seem to alternate the direction they're pointing, the first one angled away from the mouth disk, the next pointed almost straight up all the way around the mouth.

I was in there zapping some hydroids and the only two aiptasia HHers I've seen with kalk paste, and opted to let these live till I can figure out what they are. Sound like some sort of aiptasia or mojano that anyone has seen, or something else? They're definitely not ball anemones, and they don't look like aiptasia I've seen before, but I've never seen mojano in person.
 
Lots of different aiptasia types. I know the kind you're talking about, kind of alternating tentacles. Just white tips or kind of striped? Either way I'd go with aiptasia.

I had a small black stomatella once that had white on the swirl part of its shell. I never did get a pic, and never saw it again, sadly. Would really have to see a pic to ID it. If it doesn't fit into the shell like a snail, I'd go with stomatella. There's a surprising variety out there.
