I should do an update, several baby rock nems, at least 3, in the sand. They look orange. Also at least 2 on the rock as well. Makes it so I can't really stir the gravel, but that is just how it goes.
Things are stabilizing now that I don't have to feed the fish everyday, took the skimmer and peroxide doser out, and just have a bag of carbon and gfo in the UV HOB.
For quite a while the clam was on the sand, and seemed to be doing well but I really would like for him to get more light so I don't have to run the kessil quite so high as there isn't much need for those coral at the top to get blasted so much, but the little clam always get knocked out of the clam cradle at the top.
I cut a round specimen cup that I got a frag in down to maybe 1/3" tall, keep in mind these are small cups, 1.5" in diameter at most. I glued it to the rockwork at the top on a frag disk to anchor it, put sand in the .33" tall cup for the clam to sit in. So far been working great. Seems to like the sand and being so close to the kessil I don't have to blast everything else. It's not quite as pretty, but coralline will eventually cover the cup and honestly the clam is #1 and I will keep this tank up for it's entire life I love clams so much.
He also has a great deal of white growth and starting a new ridge on the shell, so at least he is doing well!
