Wee it's only 2:16 and time to sleep is running out, but I put in a good nights work. Most of these came off my teardrop maxima.

These snails look very much like the nasty pyramidelids, but I gues they can not be the real thing because of the quantity you took from your clams. Only 4-5 pyramidelids will kill a big clam easily.
The real pyramidelids will stay at the base (hinge) of the clam during the day, and will come out only at night, to "suck" the mantle at the outer rim.

Not necessarily. You could easily have that many snails on a big healthy clam.

Those lookie like pyramids to me. What worked for me was to toothbrush the crap out of the entire shell and run tap water over it. Every day. Get the eggs and the snails. You have to do it for like two or three weeks, but eventually they go away.

I have something very similar, the size of a grain of rice and smaller that I've noticed in my tank the past few weeks, I've seen them hanging off the other snail's shells and cruising on the glass.

I haven't any clams in the tank, should I remove those I see?

Edited: A little research answered my own question, it looks like that's what they are and it seems they'll feed on snails too. Guess I'll need the tweezers :lol:

They could also be a species of Cerithidae, harmless detritus consumers.
Need a picture.

It looks identical to the picture Ben posted, Mario. I also pulled several threads from (coff coff coff) dot com in which there were many pics, and it appears to be the same.

This morning just after I turned the lights on, I pulled one off a turbo snail that was hooked under the shell onto it's foot. :(

I have 4 clams in the tank. All had some sanils on them. My plan is to get the toothbrush out and brush them off the best I can. Then move them upstairs to my BB tank and get a six line or yellow coris wrasse. I figured in a BB tank the snails would have less of a chance of hiding from the wrasse. Do you think this will work?

I have had the derasa for many years and grew it from a baby. I would be pretty upset if I lost it from this. It hasnt been opening right for the last week but I was thinking it was a alk problem.

Baby Cerith usually hang out in the sand or on the rocks/glass. If there's a clump of snails on a mollusk shell they are probably Pyramid.

There's a bump on the bottom of the pyramid shell that's not on the cerithidae. If you could post a clear pic of the bottom of the shell, I could email it to a friend who just went through a course of pyramids. She'll know.

Baby Ceriths also are found in fairly large aggregations so having them on another snail would not be surprising.
I still say we need a pic of Lawdawg's snails.

Wouldn't Cerith snails likely have algae growing all over their shells as well?

If they are on the clams and the clams have been "off" for a while I would not risk them. Six lines are very greedy and seem to have a great appetite and are also one of my fav fish. Loads of action and very hardy. I would try brushing them in a bucket of their own tank water and adding the wrasse first. If this does not help then I would consider moving them and scrubbing with fresh water. JMT's

The "adult" ceriths I have in the tank are black shelled. These things are translucent white, and you can clearly see the twisting of the shell when they are on the glass, you can almost see through the shell, like it's fine bone china. Although that may just be a juvenile coloration.

I got a sixline now, so we will see.
