Royal Gramma and Azule Damsel

[clairehoekstra]

I just bought a royal Gramma today and my damsel is acting really aggressive towards him. Is this something I should worry about or will it work itself out in a little while.

Demsels are very aggressive fish I had to rehome mine because he got really nasty with every fish I put in the tank. All my fish start to hide all the time and as soon as I got rid of him they all came out of hiding and seem so calm now

Do you know what species of damsel it is?

It seems the OP might have an Azure damsel...a blue one with a yellow belly. It's supposed to be one of the less aggressive damsels. I had one. It left everyone alone but it staked out a little territory and defended it. It's not as mean as a domino damsel which goes after every fish in the tank. It just protect its territory like clownfish protect anemones.
