The odd damsel you will find to be very peaceful but for the most part, most damsels are @ssholes and can be very disruptive to a tank

There is a reason they are cheaper than a Big Mac.

An even bigger red flag is that people GIVE them away.

The yellow tailed blue damsel in my 77 gal is low man on the totem pole. Spawning Maroon clownfish pair, Yellow tang, & Singapore angelfish all keep him in line. Don't really know the outcome in anyone's particular tank, so that's probably why it's best to avoid them. The female Maroon & a Blue Devil damsel were the first two additions when I started the system & they pretty much stayed out of each other's hair. That Blue Devil was way more aggressive than the yellow tail I currently have. But like you, I really admire the blue colour. The Blue Devil died a couple years after developing some cancerous looking growth on it's tail fin. The current Yellow tail was a kind donation from another reefer & I'm happy to have him for the colour he adds.

Chromis are much less aggressive & also belong to the damsel clan, but alas, they're nowhere near as colourful. I had a group of three for a while but they all died eventually. Larger ones started picking on the smaller, one got isolated from the group & then they were all gone.

Get an Azure Damsel. They are colorful, but don't share the aggressive traits of their other Damsel cousins. I have one, and he is always been a model citizen with his tank mates.

i havd 5... 3 live in my sump as the other ones starting to rip thier fins off...

2 are in my work tank and get along fine with a killer oranger skunk clown... no way would i put these fis into my display tank... i like my other fish too much!!!

I think chromis are a type of damsel and they are very peaceful. Get a school of 3 or 5 of them and they look awesome with their flashing scales.

i might add everyone else first and then add a few damsels and hope and pray it goes well.......otherwise.......to the toilet they go. but i don't want to risk it and yeah the chromis are related but IMHO they do not compare in color.....i could have done a damsel tank with a pair of clowns and an angel.....that wuld have been good.....i'll have to think about it

don't flush them.... don't even bother with them honestly.... but if you insist on getting them, good luck catching them.. and when you catch them... they can go into my sump with the rest of my damsels!!

i would not have the heart to flush them lol......if i never got my mandarin yesterday i would have made this a damsel tank.....i doubt he would do well with them and i love him so i am not risking it

i made my work tank a damsel tank.... cheap and colorful! lol!
