Could use some input.....

[Dbarse]

Hi all, I'm having some issues and would certainly welcome any input. My tank is about 4 months old, water tests fine on all fronts, always has, salinity is 1.025.

2 clowns went in first, they are in great shape. 3 or so weeks after clowns I added a Royal Gramma, 3 or so weeks after that a Bengaii Cardinal. Shortly after adding the Cardinal the Gramma went into a rock and never came out. Then the Cardinal began showing signs of abuse, top fin was shredded and about 1/2 the size it should be however the Clowns never went near it. It went downhill quickly and passed within 2 weeks of getting into the tank. My most recent addition is a Sailfin Tang, it did great for the first few days but now has full blown Ich and is also showing signs of abuse, shredded fin tips but again, the clowns dont go anywhere near it. Clowns are still in great shape.

Any ideas/thoughts on what in the world is going on??

Thanks.

Sorry, forgot to mention my tank is a 90 gallon.

The clowns don't go near it, that you see, but Clownfish are very territorial, and some of the meanest fish in the tank, and I've seen em chase a full grown Sailfin Tang before, in my tank.
