Breeding galaxy rasbora.

Would like to see if anybody has had any success breeding these fish.I am looking to get a few soon and will try to breed them.From what i have read this great looking fish is already in danger and all fish keepers who purchase them should try to breed.This would be my first attempt at breeding so any advice on tank size,filtration,lighting,water temp would be a great help.

This fish has gone trough so many name change in the past 2 years. I think the latest official name is Danio margaritatus. No longer a rasbora. But i think we will keep calling it galaxy rasbora until they rename it, again.

I have bred these with limited success in the past. The young also had very faded colouring so i stopped breeding them.
I used to keep them in a small 20L tank, sponge filter, Temp 22-24c (same as their natural habitat), pH 6.5 and some java moss.
I placed 2 pairs in the tank and fed them mostly live foods.
Eggs were found in small numbers on the moss but they had very little adhesion and would drop to the bottom of the tank if disturbed. I suggest keeping the base of the tank clean to prevent fungus.
Not to long after getting them and breeding them a few times news came out that the water were they came from was hard water. So i slowly changed them and the fry to harder water. This was a bad idea. They dont do so well in hard water. Breeding stopped and i lost most of the fry shortly after.
After speaking to a couple of people keeping these they agreed softer water is better.
Once i slowly changed back to softer water they bred again.
On a recent trip to the UK i spoke to a breeder of these and he pointed out that raising the temp to 28c gets much better results with breeding. I would only do this short term and not keep them at this temp. indefinitely.
When the fry hatch they hang around the surface, so i suggest floating plants for cover. If the surface is dense with plants all you have to do to collect the fry is push the plants down with your hand and collect the floating fry from the surface with a net.
You can keep the fry in a breeding trap with the same water as the parents until they are 1/4 size of the parents. They wont eat them at this stage. I have found some fry survive in the tank with the parents.

I hope all goes well with your breeding project. Darren

Thanks for the advice Darren.Should be an interesting project for me and hope i have some success.Time now for me to get a breeding tank.I think a small clear seal should do the job so if anyone is selling one let me know.

Orca i have just started to breed these fish again from the ones i got recently.
This time the fry stay very low in the tank for the first 3-4 days.
If you plan on leaving the parents in the tank i would suggest placing some java moss in a section of the tank for cover for the fry.
If you plan to just place a pair in a tank for breeding and removing them again. You wont have a problem with the parent seeing them as food.
I would still use the java moss as a spawning mop/site.
