Clam

[Lucasb625]

I am looking to get a clam that is blue but under 50$

I think Sea Clams: Tridacna Clam Species for Marine Aquarium Tanks has some. I have never purchased anything from them, but I have looked at their site a few times. This is just one off the top of my head. You can search for saltwater clams, and you should turn up many different sites. Hope that this helps.
