zoos do not do well in my tank? help? comments...

[packfish]

I can keep a variety of corals, but small zoos always seem to die out on me. I can keep the larger ones, I think they are called zoas? They have more of a stem and a larger head. Not tight small zoos, I cannot keep. I have also found I cannot keep xenia.

I have frogspawn which flourishes, lots of mushrooms, leathers, and several fish for over a year. Nothing has died. CLowns have even reproduced eggs in tank, and I have noticed sponge starting to grow on a coral. I do water tests and everything is great.
any thoughts?

We'll need a bit more info on your tank's filtration, lighting and water parameters.

I know one thing and that is that xenia like alot of nutrients like nitrate and phosphate. They dont like to be in really really clean water.

i agree that xenia likes nutrients, mine spread like weeds when my bioload was greater and did less h2o changes.
