Oops.
Sorry Sunny. I forgot to answer your question.
1. Yes, I did have some problem with the clam on the sandbed. Eunicid worm will harm them if they are not so healthy.
2. I use Two Little Fishies' AquaStikâ„¢ Underwater Epoxy Putty to attach coral.

Thank you for remembering me, Ching. :thumbsup:
The reason I ask about the clams is I have a very healthy derasa for about 4 months that is currently sitting on the sandbed (1.5") and I certainly don't want to lose it. I've tried putting a rock under the sand for it to attach itself but so far no luck. I trust your skills as I've seen your consistently amazing results. So you don't put any rock under your clams or are they sitting on the eggcrate?
