Strange behavior

[kaiserpup]

I noticed a few unusual things this morning. I bought a peice of live rock with mushrooms growing on. I kept finding my crab on the rock (I think he was eating the mushrooms.) and kept taking him off. This morning I noticed some of the mushrooms were either gone or closed up?
My blue damsel has almost turned clear and he's zipping around more than normal. He's going up to the side and hitting it several times with his nose, before going to the other side and doing the same thing. (Maybe he ate some mushrooms?)
Also my black cap keeps running back in his cave, and he looks like he's covered with sand.
Is there something going on, or do they just act weird occasionaly? (The last time I thought the crabs were acting stange and being very still they did finally molt.) <img src="graemlins//eek.gif" border="0" alt="[eek]" />

Well all seemed alright last night and this morning. I don't know what happened the night before, but I guess everyone got over it. The damsel turned back to his normal blue and stopped hitting the walls. The Black cap is slowly coming back out again and he looks just fine. The mushrooms seem to be all there too, they opened back up. I didn't know they could close like that. I haven't seen the crab near the mushrooms since I pulled him off last either. I don't know what could have happened that one night, but I guess I'll have to get used to mysteries with this hobby.
