The Domino Dilemma.

Hello people!

I was recently skimming over Liveaquaria's saltwater section when I came across a "Golden Domino Damselfish". I've got to tell ya, this thing is cool! It has a subtle yellow and grey color, and a squat sort of body shape that almost makes it almost ugly (right up my alley). I instantly decided I had to have it. So began the research, and the difficult task of sifting through 1,000,000,000,000 results that Google came up with in just a half a second. As I'm sure most of you have noticed when trying to learn about a new fish 40% of the results aren't even related to the intended search, another 40% is conjecture, and the remaining 20% is completely contradictory to itself.

My first task was trying to figure out if the coloration I thought was so awesome would actually last into adulthood. Google Images proved unreliable, and so did everything else. I came across people saying it turns pure black, or it turns pure grey, and even it developing stripes. The lack of consistent information only lead to more confusion. Do they shoal? Some said yes, while others said for the love of God, don't even let it see another fish for it will surely destroy it. So then I was faced with another question. Are these the demon spawn of an already aggressive group of fishes? I spent hours trying to find trustworthy answers, and have decided to share it here in the off chance someone is running into the same problem.

Here is what I learned.
Dascyllus trimaculatus, Dascyllus auripinnis (my Golden Domino) dascyllus strasburgi, and dascyllus albisella apparently share some of the same common names creating an awful lot of confusion. Even when searching with the Latin names you come up with muddled results. Understandably so as location apparently has a great deal to do with both coloration and markings. D. trimacalatus, and D. auripinnis were thought to be the same fish until 2001 when John E. Randall and Helen A. Randall took a closer at the taxonomy. What their motivation was I don't know. What I do know is that they described a new damsel. They found that it has one less gill raker, shorter paired fins, and a slightly larger size.

It will shoal, and is aggressive as the typical damsel. I ordered 5 and they should be here on Wednesday. Time will tell if keeping a small number of them allows them to feel more secure and thereby be a little nicer, or if the gang mentality sets in and makes things...interesting. I don't know if you will ever need this information or if it is even helpful, but at the very least I hope it comes up in the Google search of some poor soul who went through what I did.

Here are some links for further reading should you be so inclined.

I hope I didn't bore you or beat a dead horse. Has anyone kept these cool little guys?
 
lol, they are common fish that, are total maniacs, get big, and love to terrorize other fish, often times, regardless of that fish's size. The can do a lot of damage to fish several times their size. I would avoid them or keep them by themselves..
 
Domino damsels start out all black and then develop some gold-brown coloration when they reach adulthood. They are NOT community fish. They'd be a cool thing to put in a species tank, though, they're intelligent.

Even so, if what I ordered are truly what they are supposed to be I will be happy. The only inhabitants in the tank right now are a black ocellaris who is a huge dick, and a one eyed Talbot's damsel who was a rescue. I don't really have the intention of keeping the standard "community" tank. It might sound weird and a bit OCD, but most community tanks seem too chaotic to me. All the different species and colors seems almost distracting. I like things more uniform lol. Not that I don't appreciate the beauty of a diverse community tank it just isn't my taste. I like oddly shaped understated fish the most. With that being said, I don't plan on keeping much else in the tank (if anything) aside from the Dominos. It's only a 55 gal tank, and with all the rock that brings my overall volume down. On the off chance I do decide to throw in something else it would have to be equally aggressive, and probably black or deep blue. I like the color to come from the coral. So there are my odd standards and intentions. Don't hate too much lol.
 
If you are going to do a dedicated system, have you considered a pair of Dascyllus albisella? I think they are beautiful...

They really are. My Golden Dominos came in today. They're even cooler than I'd hoped!
