Mine killed a tomato clown then an anthias and was trying to kill a foxface that was like 6 times it size...lol Crazyest fish I've ever had, my whole family still talks about the time Speeder (kids named it) went loco on our fish.

Don't get damsels... they are very aggressive and will attack anything and everything. I used to have 25 blue/green chromis in my tank, now I have five. Guess what happened?

Yellowtail Damsels are tame. I have them in lots of tanks. Some are tamer than others, but maybe these guys had Yellow belly Damsels???

My yellow tail damsel is a model citizen. No aggresive behaviour and ive had him/her for 3 years now. Previous damsels were never mean either.

I think Myka maintains tanks for other people so her opinion on them counts for more then a single person/tank.

Chromis, clowns, and what we refer to damsels are all apart of the same family "Pomacentridae". Their all a type of damsel and they can all be territorial and agressive.

Im not sure what youre after here, you want input on your stocking list but youre also not willing to alter it?

No I'm willing to alter it. Just the ones I have stars beside I would be more sad taking off the list. The Anthias I have starred because I know I want some, but not sure on species/ numbers

Most of the commonly available Chrysiptera species are pretty tame compared to other damsels (barring Fiji Blue Devils, of course). That said, mixing them is like mixing cats. Some get along with other fish and each other. Some don't. There's also a few other considerations:

• Are they the dominant fish in the aquarium?
• When were they added in relation to the other fish?
• What is the total stocking density of the aquarium?
• How often do you feed the tank?
• Have they previously killed off other fish?

These are all variables that are going to greatly influence the behaviour of any given fish. If you want the best chance at it, here's what you do (IME):

1. Make sure they will never be the most dominant fish. This should be easy if you have a tang or a big anthias male.
2. Add them last or, at the very earliest, after the biggest, most intimidating fish has become comfortable in your aquarium. This doesn't necessarily have to be an aggressive fish (Naso Tangs come to mind).
3. Keep the stocking density medium - high for normal compositions, low if you have only bigger, more intimidating fish outside of the damsel.
4. Don't 'inherit' problematic fish from other people.

Thanks!

A Kole Tang would be better in a 90 gal but if you really love Yellow Tangs, put one in last as it might not allow any other tangs (and maybe other fish) in your tank - my experience. My yellow tang killed my Kole and my Hippo.

I have read that yellow tangs need a MINIMUM of 100 gal. which is maybe why they are so aggressive in smaller tanks.
