sick yellow tail blue damsel

[mr.limpet]

Hello,
I noticed a few days ago that my blue damsel's tail fin is degenerating, and now his color is fading.
Just did a 10% water change (12gal nano) All my water parameters are within range.
Just added a clownfish to the tank yesterday, and I've seem him nipping at the blue damsel.
Is he sick or is he being killed by the new clown?
My tank is stocked with:
1 damsel
1 clown
2 turbo snails
1 coral banded shrimp
Live rock, live sand.
any ideas would be appreciated.
thank you
Mr. Limpet

Are they degenerating or are they being nipped and eaten by an aggressive tankmate??

Ya that be my guess, agressive tank mates love a little tail

Well, sorry to say my damsel died. This is the third fish that has died on me since I set up this tank 2 months ago. The first one was a damsel, but he was never healthy from the get go, never ate. The second was a clownfish that died the day after I overturned the sandbed to clear the diatoms. Guess that wasnt a good idea. Now this damsel dies.
I dont get it, I've been meticulousy maintaining this tank. Doing my water changes, checking parameters, feeding a varity of food. The only survivors have been my coral banded shrimp and the snails. Now you would think that if my water quality was bad the first one to go would be the invert.
about ready to give up on saltwater.

It's best to have the tank up and running for at least 3 months before you add any fish. At least your damsel only costed you a few bucks. It sucks when you lose a fish you paid over $40 for.

Chances are there is a step somewhere in your routine that is flawed. And in a Nano things are harder to begin with.
Slight differences in water can cause huge fluctuations in water parameters in a nano, thus causing a lot of stress for the fish.
Nanos are harder plan and simple...cheaper...but harder...
