My quirky, buzzing, cloud-making damsel showpiece...

I love damsels. My favorite tank is a damsel reef. I'm pretty good at it. I don't have nipped fins or the like---and one of the keys, I think, is, a) keep it to one of a kind and b) figure there's 'one ring to rule them all...' or, there will be a boss damsel, and some species are more apt than others to take that role.

My dark lord of the tank is actually a golden onespot dascyllus---size and shape about that of the smaller tangs, brilliant gold fins, brown body, white spots, and, well, she buzzes like a rattling teacup in an earthquake when she's ticked, or grabbing a morsel of food: the other damsels kowtow to her, but run right back in behind her back. First time I heard her sound off, I thought something had gone wrong with the pump. Loud!

Her latest---I passed my tank and feared I'd just had a kalk overdose---until I saw a white stormcloud come out from under the rockwork, driven by a bright gold tail.

Well, that's one way to clean your sandbed.

I actually have two dascyllus species: her, and a smaller three-stripe b&W that I think is Romeo to her Juliet, and who knows what we'll get if there's a mating. I didn't want a mated pair (problems) and thought those two were far enough apart this wouldn't happen, but, ah, me, he is staying small and she's the biggest thing in the tank.

Their behavior as a species is the same as the maroon clowns, and they actually will adopt an anemone with all the same behaviors. Exactly the same behaviors. I can say somewhat gratefully that if she has teeth, they're not visible (my bucktoothed clarkii clowns of yore were really biters) and she'd rather buzz than bite. Their other name seems to be 'humbug damsel.'
 
Love the blue/yellow damsels!

In my 75, I have:

Yellow Tail Damsel (Chrysiptera parasema) 2-3" plus an

Azure Damselfish (Chrysiptera hemicyanea) 2-3".

In my 180, I have another Azure Damselfish.

I have never had a marine/reef aquarium without at least one of these beauties in the DT.

One of mine is a blue star damsel---always was a disappointing grey until I changed to LED lights---shiny blue. Chrysipteras seem to be ok with dascyllus species. Not so much the pomacentridae (chromis). The dascyllus run the show, and (in my tank) each has a castle---two spires of lacy rock. The vassals (chrysiperas) live down in the structure and the two dascyllus each rule a separate spire---but trade about, a sort of mobile feudal system. They ignore the gobies and basslet, who come and go as they please. One thing the tank has got is constant motion.
 
I have a yellowtail dascyllus that has been in the sump ever since I got it. I'm apprehensive to put it into the DT for fear of not being able to catch it if needed. My plan is to wait several more months that way the other fish have time to grow.
 
Yellowtails and azures are fairly small damsels: they look a lot alike. Azure is more aggressive: yellowtails are much milder. They are indeed very hard to catch: they live in holes in the rockwork and will go there real fast if threatened. The main thing to keep them peaceful is to be sure that everybody who wants a hole has a hole. They get terribly stressed and turn aggressive if they can't find a free one as it gets dark. They will try to take one if that's their only option. If your tank has a lot of nooks and crannies it should fit in fine, as other fish will take the larger holes and his needs will be limited by his size.
 
Hi Sk8r,

How many damsels do you have in your tank now?
I have a 120 (4'x2'x2') with a fair amount of rocks in it. I already have a pair of yellowtail damsel in the tank for about 6 years now. I also have a 12 years old female Fiji blue devil damsel fish in another tank. I think its female because of the top, bottom and tails are all yellow. Lately I want to shut down the small tank and put the Devil damsel in to the 120 gallons with the 2 Yellowtail but I am kind of afraid it will kill one of the yellow tail and take control half of that tank. What do you think about this? Any chances that all 3 will live happily together? The Devil is bigger than the Yellow.

Thanks
 
I avoid damsels like the plague I worked at a lfs and saw a 9in clown trigger get destroyed by a trio of Sargent majors

I'm glad you enjoy them though they are quite the little critters as far as personality goes
 
I am forming a perhaps iffy theory of my own, only based on several damsel setups I have done through the years, and not on observation of more than videos of the wild. There seems, in an area of reef, always to be The Overlord In mine, boss is the Golden One-spot Dascyllus, aka Humbug or Golden Domino. It has a 4" max size, which is to scale with everybody, all 4 or under, and nobody else looks to be reaching max. I think the boss fish inhibits growth of the others in their area, especially in a tank.

Smallest is the azure, next the chromis, then the blue star and Fiji devil, and the b&w 3-stripe dascyllus. The Golden masses about 3 x the size of the Fiji devil, and pretty well dominates, though the other dascyllus, the 3-stripe, lords it over whichever of the two spires the Golden isn't presiding over. The non-damsels just go where they like, respectfully, but are never bothered: that's the goby pair, who are about 4" long, the gramma, etc.

There's chasing among the damsels, but no nipping and ONLY the Golden chases. Everybody else just moves out of Golden's way...I kind of think the Golden is female. They are VERY similar in manner and habit to a Maroon Clown, and seem to be focused only on other damsels. But again---no biting. Just buzzing (which may vibrate fishy nerves literally for all I can tell). At least fins are never touched.

I think in a reef community the damsels seem inclined to have 'their' hole, their territory, and to stick lifelong close to it. At least that looks like the pattern of behavior in my tank. They might seek new holes now and again as the neighborhood gets tougher, but by dark they have to have found one hole to claim, or face a night exposed to predators.

The dominant in the area shoves everybody around, but damages nobody. So the whole little community may be dependent on the warning and toughness of the 'boss fish' to spook in a timely way and get to the holes if a predator comes near, and to ward off other claimants of their holes, which are smaller than the Boss needs.

That's my theory, anyway, and it works at least as far as manaqing a quiet damsel community. There's a boss, and there are underlings. Your Fiji will boss, the yellowtails will duck and run, and the Fiji will stay in charge unless you move in a dascyllus or Blue Velvet, which tend to become large, fat, and attitudinal. I'd be surprised if the Fiji would kill one of the yellowtails as long as there are plenty of holes to go to. They'll all tend (I suspect) to focus on each other and pretty well ignore other inhabitants. Except chromis. To my observation, nobody likes the chromis, who cluster together and race through everybody's little territories.

Is there any chance you'd post a picture of your tank? I love all the activity damsels bring, but learned the hard way what else they bring.
 
I have a couple of yellow tails in a 180. I have never had any problems with them at all. They both seem to claim their own side of the tank and will even swim together at times. Though at night they both go back to their own side. As far as all the other fish they seem to ignore them and have never chased them at all.

I think you missed the part where I said yellowtail dascyllus (Dascyllus punctatus) not the average yellowtail but more like your golden 3 spot.

She is definitely going in just not anytime soon.
