Galaxy Rasbora aka Pearlescent Danio

I just saw this particular fish for the first time at the fish shop that I frequent. Apparently they are a recently discovered species from the lakes of Myanmar. They are so small and beautiful, only grow about the size of a neon. I would love the keep some in my tank, but i'm reading that they are already over-fished. I suppose we are all encouraged to boycott buying these fish. Anyone know anything else about them?

I too was considering getting them, and then had the concern for over-fishing. I will post a response to my concern given to me by Bettababy (Dawn if you're reading I hope it's okay that I posted this!):

"When a wild species of fish (or any other animal) enters the retail industry, if popular, there is a good chance people will begin to keep them simply to learn their habits so as to breed them in captivity. Once these animals are successfully bred in captivity, this does 2 things. The first, and reason I mention it is that it decreases the number of fish caught from the wild environment. The 2nd thing it does is help to prevent the extinction of these animals from our planet.

While you may perceive them in the light that buying them will further lower their wild population, thus you don't wish to contribute to that... I ask that you consider the other side of that coin. These fish are going to be caught and collected anyway, whether we like it or not. While you may save a few by not purchasing them, you also would not be contributing to the survival of their species.

While I do not promote the going out and purchasing something that can't be properly provided for just to ensure the survival of a species, I see no reason why you could not accomplish many things with these fish. You have the ability to properly provide for them, you have a desire and liking for their species. You have enough space in a 30 gallon tank to make your aquarium species only, and thus a learning experience that could contribute to their overall survival, and maybe find a missing link on how to get them to spawn in captivity... and at the same time, provide you a wonderful aquarium experience."

I have to say I agreed with her on that. So when I went to the fish store to purchase them, even after doing a ton of research on the care of them and their compatability with my tank population, I decided against it. They were so tiny, they have to be fed micropellets which makes it hard for them to compete for food, and I was worried that their tank mates would nip them, although now I am convinced they would have left them alone because they interact with each other fine.

Anyway, just my opinion.

ps if you like this fish and want something easier to keep and something a little bigger, I got leopard danios. They are beautiful, and visible. Similar patterns but different colors.

I like that post. A pretty good answer to my question. It would be a neat aquarium specimen, though they do seem very fragile. I only keep a community of very small tetras and corys, so they would probably be fine in my setting.. but it's something I'm still thinking on. Thanks for the input.

I wonder if anyone has had luck with breeding them?

That's probably one of the best researched, well thought out, and most intelligent commentaries on that particular subject. The logic is inescapable. I can attest to similar conclusions concerning White Clouds, which some of you may know are my favorite fish and the only one I keep atm. White Clouds are now extinct in the wild and only survive on fish farms that produce them for the market. If the production in captivity had occurred sooner and in greater quantity, there is a possibility they would still survive in the wild. Unless of course the collection of them for the commercial market from the wild was not a deciding factor in their partial extincton.

Yes the celestial danio (another name) has been over harvested. I remember when they first hit the hobby, they where in high demand and still are. $30 a fish was common in the beginning. They were vulnerable from the beginning as they populate a very small area. They are fairly easy to breed in the proper setup and I'm sure you can find lots of info online pertaining to this. I've seen them in shops, but I'm not that attracted to them.

Captive breeding IMO will/has taken off with this fish. As numbers in the wild decrease, catching them and exporting them becomes quite difficult and expensive as more time is put in for fewer fish. The cheaper method is for the fish farms to breed them, especially with a fish that is in such high demand. As far as I know most of the ones you see in stores are tank raised today. I'll have to pay closer attention to the exporter lists I look at. They normally list the fish as wild, captive breed, or german bred. A 10gal is enough to breed these fish in the right water conditions.

As long as the harvesting is reduced, which usually happens with captive breeding taking off, there is no reason(that I know of) the wild populations will not recover.

I currently own some wild caught fish from Myanmar. Garra flavatra in my sig. Also newer fish, entered the hobby only a year before the celestial daino. One farm started breeding them in 2008. I hope to breed mine as I really love them. They have a large wild population, so are not at risk for over-harvesting. They like to hid under/between rocks when scared. Making them time consuming to collect.

I myself am interested having seen some of them in one of the fish shop in my country. It goes for 5.50 dollars for one.

When i went to another fish shop or should i say fish farm, they have this same species but lacked the red color on their fins, thus, it strikes my mind if they are tank breed or not. Will ask them when i visit the fish farm the next time.

Anyways, there are very interesting fish and is cute! Heard they are hardy.

Good to hear that they are hardy. Out of curiosity, does anyone know what tank level they swim at?

They swim at all levels but they stay mostly at the middle-bottom of the tank.

Thanks for this post. I have just found the fish (Galaxy Rasbora) for my new 75g. Maybe I can fit 50 or so in there and breed them too. Anything known about their breeding habits?
