Why no Zoas or Clams?

[daniella3d]

For zoanthids, it is best to dose with vitamine C if you are having problem with them without any obvious cause like parasites etc... For the clam, you may have introduce something with the new corals you added? Check for snails on it at night or other parasites. Does it have pinched mantles? You have a lot of angelfish, maybe some are nipping at the zoanthids and clams?

Also how did your anemone exploded? how can an anemone explode? Not sure I understand what hapened there.

Are you using carbon? if not, it may help remove what ever toxin is left in your tank.

What ligth are you using? maybe before you had more nutriment in the water and the clam did not need as much light? For the zoanthids, maybe your light is too strong or not strong enough, or maybe some parasites?

REally hard to tell without knowing more detail.

Did massive water changes and ordered new coral.

Been a couple of months now. All the new coral is flourishing (same coral as above) but I can't seem to keep clams or Zoas in my tank. They die within a couple of weeks or close up all together.

What do you think it could be?

I do 10% weekly water changes.

Nitrates around 10 or less.

Ammonia is zero.

Nitrites are zero.
