Clown Fish help!

[triggereef]

just a suggestion..

The same thing happened in my tank and about a month after my clowns dies i noticed a crab in there that must of came in on my live rock.. Well i noticed that he wasnt very friendly and thought that might be the cause of their deaths..

mabey you might have the same problem...

my first thought is acclimatization. Did you get the clowns at a different store than the other fish?
What do you keep your Specific gravity at? Some stores keep their sg lower than we would have in our home aquaria. Did you happen to compare the store water to yours?
