Thoughts on yellowtail damsel in 120 gal tank.

[benjc]

I really like the coloration and have read that they are one of the less aggressive damsels. Wanted the opinions from people that have had yellowtails as to how bad they really are. Current fish include 2 clownfish, 2 firefish, 2 blue green chromis, 1 bangaii cardinal, 1 melanurus wrasse, 1 yellow tang, 1 kole tang, and 1 diamond goby. Future fish likely to include longnose hawk, leopard wrasse, 1-2 flasher wrasses, and if I can find a pellet-eating mandarin, one of them as well.

Again, I know some (like the Fiji Devil) are extremely aggressive; looking to hear people's experiences with the yellowtail damsel (Chrysiptera parasema) or possibly the blue damsel (Chrysiptera cyanea).

Ive had 3 yellow tails in my 220g for almost a yr now. at first they all got along, then there was some bullying to figure out a pecking order, but now all is well. very vibrant and active fish. just do understand the clownfish, chromis, and damsels are all in the same family. so there might be some aggression. they will def leave the tangs and wrasse alone obviously. if the firefish seem intimidated by them, the damsels could target them, but if you have plenty of rock work, then I don't see why not giving it a try, adds mucho color to the tank...

i would suggest either the yellow tails or the azure damsels for your system...

Thanks for the input. My firefish are ignored by everyone, the chromis do their thing, and my female clown is a pain to all passive fish; I had to sell a 5-inch pink margin wrasse because of her. Next time I setup a QT, I'll probably toss a yellowtail in. Worst-case I'll have to get out the fish trap.

I have two in my 180 without any issue. They set up shop on opposite sides of the tank and neither will cross into the others territory. they don't bother any other fish including chromis.

I've had one since 2008 and its never bullied anything. I've never even seen any aggression.

I have been wondering the same thing. I have a 5-foot 100g FOWLR that only has a perc clown and a melanarus wrasse in it so far. I was thinking about trying a pair of yellowtails since they are supposed to be fairly docile and I have a tank with enough room for them to claim a hole/territory. They are cool little fish and I've never had a big enough tank to mess with them until recently.

My only reservation is that I don't want them to harass/kill new additions. I'll eventually add a yellow tang and a dwarf angle once I find healthy ones.

The yellowtails or azure damsels would be fine. Be sure to introduce all the damsels that you want at once as after they establish their territories newcomers are likely to be killed.
Another good choice is the allen's damsel which is more passive, but a different hue of blue/yellow.

I have had my fair share of damsel horror stories, but never with the blue yellowtail. That and the green chromis are the only ones I'd add to a tank without concern. Single specimens are probably best.

Yellow-tail blue damsels are one of my favorite fish. For what it's worth -- I kept 2 in a fairly overcrowded 29g about a decade ago for 4-5 years. Never bothered each other or other inhabitants...even new additions. Great little fish.

I plan to get a pair for my 65g non-aggressive tank with a marine betta and potter's angel as the main fish.

yellow tails r great fish. only fight among their own kind. very tough fish and was the fish to survive a power outage I had awhile back while away from home.

I have four in my system with no problems.
They do, have their own territories.

I was wondering about adding two as well to a 210 (72x24x28 with 350 lb. or rock) but have been concerned how they would get along with a trio of Royal Grammas and potentially juvenile Leopard Wrasse sp. Any thoughts?

 

[SNAKEMANVET]

I had a pair in my 28 jbj,they wouldn't bother other fish and they laid eggs often.

 

[Rockster2599]

I had some Azures and they need space, about a foot a piece. I got 3 for my 2 footer and 1 set up a territory at one end and the other at the other, the third was stuck between and took a hammering so they had to be moved on. It's a shame because they were gorgeous

kept a pair in a 125 for years with no issues.. stayed on opposite sides of tank every now and then they would meet in the middle for a quick battle then disperse. they were cool. ignored everything else in tank.
