Did my royal gramma do this?

[Alex33xKV]

Hi,

a week ago I bought a royal gramma, it has refused to eat and hides whenever I come close to the aquarium. I've noticed that it has been aggressive towards my clowns, and roughly 5 days after I had bought it, I found my tuxedo urchin floating around, and a day after that I found my cleaner shrimp in pieces on the sandbed. Could my gramma royal have done this? I checked my ammonia and it's 0 - so couldn't have been ammonia.

I can't imagine it attacking an urchin with sharp spines.  However, shrimp are particularly sensitive creatures.  Sounds like something is off (who knows if it was a salinity change or something else).  Hopefully your basslet will start eating soon.

How long had you had the tuxedo urchin?

 

Is it possible the cleaner shrimp had simply molted? Sometimes their molt shells look like a dead shrimp.
