Order 14 of the new galaxy fish, want to breed them anyone working with this fish in the terms of breeding . Also working with the flag fish they seem to just breed like rabbits

Do you mean the new galaxy rasboras? If so your in the wrong forum, they are actually cyprinids. There are a few posts by others who have them, maybe they have had some luck breeding them. They are a relatively new fish and people haven't had much time with them.
This one post is about breeding
http://www.fishprofiles.com/files/threads/32950.1.htm?2#
and this one is someone else who has them

What does that mean, Bob? "Till the cows come home." Where have the cows been?

Breed Galaxy Rasboras?

If Paul Dixon at Bolton Museum is anything to go by (he was one of the first to spawn them) then you should be looking at soft, acid water, possibly peat filtered, modest currents, LOTS of Java Moss as a spawning medium, and it's also possible that instead of spawning as individual pairs, they are communal spawners, though this is a detail that hasn't been revealed in depth to date.

Fry are going to be practically microscopic when they hatch, so infusoria is a must to feed them. Start firing up a batch of infusoria cultures on a cyclic basis to make sure you have enough to keep the babies going, because I suspect that they'll need infusoria for at LEAST 21 days once they have hatched, unless their growth rate is prodigious and they can move on to newly hatched Brine Shrimp at an early date. Remember that the adults are tiny fishes when fully grown, so the fry are going to be ridiculously minute.

Oh, and don't forget to read those other threads linked above as well.

I tried the links you listed the 2nd one doesn't work. Thanks to everyone with info. I have read all I can find about this fish. does anyone know of a organization for this fish.

Here is an article about breeding them.
http://www.practicalfishkeeping.co.uk/pfk/pages/show_article.php?article_id=557
Note: you will need to make an account to view the article.

These are very new fish that are becoming endangered already, captive breeding is imp[erative for the wild species to have any chance of regenerating.

Are you sure they require acidic water for breeding, Calilasseia? The Practical Fishkeeping article states that the water in their natural habitat has a pH of 7.3. Unless there are signifcant water chemistry changes from season to season, they should spawn fine in alkaline water. The guy I bought mine from was keeping them in moderately hard water with a pH of 7.6, and they appeared to be in spawning condition (many of the females were ripe with eggs and had males chasing them).

These are highly adaptable fish, however, and do not seem to be picky at all about their water parameters. More important is the temperature of the water... According to the article they should not be kept above 24°C. I'm keeping mine at about 21-22°C and they are thriving.

I was working on the basis that their habitat was similar to that of other Rasboras. If they'll spawn in alkaline water, even better. In fact, if it proves to be the case that they're not picky about their spawning water, and just require lots of Java Moss, I for one am going to be delighted because it means that once commercial spawning takes place, it's going to be productive. Which means it'll eliminate the need for wild collection in fairly short order, which can only be a good thing.

At some point I'm going to have to see if I can contact Paul Dixon and find out what water chemistry parameters apply to his spawning Galaxy Rasboras.

Yeah, I read everywhere about how Dixon was the first person to spawn them and everything, but I haven't seen any more details in regards to the methods he used to accomplish such a feat. I'm still trying to get my water parameters closer to that of their natural habitat by doing weekly water changes with only distilled water. The pH of the tank is 7.6 now, but when I filled it up last year with the Davis tap water (big mistake), the pH was 8.8 or higher.

Galaxy Rasboras seem to show much more affinity to danios rather than rasboras (particularly true Microrasbora), in both their relationships to each other and in terms of their care and breeding. As you predicted previously, the main issue is probably not getting them to spawn (that doesn't seem to difficult at all), but rather raising the ridiculously small fry once they hatch.

By the way, has anyone heard when the Galaxy Rasboras will be assigned to their new genus? It was supposed to happen before the end of February. I informally proposed the name Microdanio here last year...

Hah... I just noticed something else about the Galaxy "Rasboras" when I was feeding mine - they have barbels. If that doesn't scream "danio", then I don't know what does.

(For those not so familiar with Cyprinid anatomy, no rasboras have barbels, while danios do.)

I'm not your neighbor, you Bakersfield trash.

All microrasboras are more closely related to danio/devarios than rasboras themselves... in fact, in most circles,micros are considered danionins. Celestichthys margaritatus, is however, neither microrasbora nor danio. Poor things, though...just described and already going extinct. Humanity is a sad thing to behold.

Are you sure they have barbels?. My friend have some & i cannot see them.........

They have rudimentary barbels.

Thanks alot Cup_of_Lifenoodles & i'll check again.


Has anyone saw any pictures of the Galaxy fry?.

Order 14 got 17 fish, not complaining, all sevived the shipping and no deaths. I do how ever have clusters of eggs in different places in tank> I not sure what they are snail or galaxy. Just know when went bed they were not there. Just have to wait and see.

Galaxy are egg scaterers..... If you have a cluster of transparent eggs, then they are snail eggs.

Never seen snail eggs like these. In the gravel and in the micro swords. If they are snail eggs than they are snail eggs. I never searched for eggs before,always just help little fish let move you to a safe tank. LOL Thanks
