What type of mollusk is this? Photos

[Aaron1100us]

I've had this for allmost a year, I bought some mushrooms that were attatched to it. You can see the opening in one of the photos if you look close enough. There is another opening just like it. There isn't much left of the shell but that is what the mushrooms are attatched to. The opening is in the middle of photo 27. THanks.

Hey man,

Not sure really, just wanted to ask how the 29 is coming along?? Did you go with the 250's or 400'S?

HI, how are you doing? My tank is doing great finally I went with the 400w. The bulb is about 8 months old now and I think I'm going to with the 20k XM soon. I think I've heard you say some pretty good things about them. I posted a before and after thread for my sebae anemone. Wow, did that light ever make a difference. It went from pure white to brown in a month. And I just got my refugium hooked up the other day. How is your tank doing?

Nice,

I have the XM, and it so far seems pretty good, I had no other Metal Halide before this bulb so I really can't make a difference of which bulb is better or not...
So far so good. Nice coloration, but the color I'm starting to dislike... just me..
