New shrooms

[Kimdive]

Hi there, I have just bought some red and blue Actinodiscus shroom's (I think this is there name), they were already on a rock.
They have been in the tank now for 2 1/2 days now and have yet to open up. How long does it take them to acclimatize to there new surroundings or should I start to worry?
Thanks

:confused:

Wow have I phrased this wrongly or does no one know the answer??

This can be a really variable one, I found that when I had fewer corals in my tank was when my mushrooms opened up the most and stayed open the longest. They are durable so they can be shrunk up and unhapply looking for some time before dying. Just be sure they are not crowded by other corals, except for other mushrooms, for some reason other mushrooms of similar size seems to actually help them stretch out. Also make sure they are not being cooked by being placed too high in your tank. That's about all the advice I can think of though, hope it helps.
