My LFS has a few nice clams that are well priced and I'm curious how difficult and hardy they are. So far I'm doing good with the corals I have, zoas, shrooms, gsp and some leathers. I need something to put down low and I would like something blue. Everything I have is green and/or red/orange. LFS has a lot of nice 3-4inch tall pieces of green acro but I'm tired of green!!!
