Some updated pictures
It's been a while. I have had no problem with the cowfish in the reef, he has not picked any corals and pretty much eats everything but flakes. He is in with a pair of percula clowsn, sailfin tang, two clow gobies, watchman gobie and a couple of fresh water mollies, I just got babies too.
For the clams, you need good water quality, stable environment, good lights (I break this rule), lots of calcium, MG,
ALK. All I do is water changes and 24/7 top off water with
kalk.
