Okay cool. I have been taking with the guy a lot about it and may be able to get it for what he paid plus a little and not have the normal markup. so I am thinking 250 or so. He is asking around 350-400. I will probably get a yellow wrasse.
Honestly, if you want the clam you should get it. Just buy a yellow Coris Raised too and you shouldn't have any issues. How much are they asking? Maybe you can get it for a discounted price?
The snails can get up to 1/4" long. If the snails you saw were 1/2" then I doubt they were Pyramids.
