FK Galaxy Rasbora Breeding Program
#1
Celestial Pearl Danio/Galaxy Rasboras (Celestichthys margaritatus)You may have heard a lot about these little fish. They were first discovered back in September of last year and unfortunately they are already under threat due to massive over-fishing by the aquatic industry. There is little information on them as they are so new so pooling information and discoveries is essential to ensure successful breeding. They are still available in some shops but PLEASE do not buy them unless you have the facilities, time and experience to breed them. Unless they are bred by aquarists then they will die out in the wild. Their only chance is if we can breed them in captivity.
This thread is intended as a resource and information pool for breeders. We can exchange info on care and spawning and also swap fry to ensure a larger gene pool. Please add any information you have- no matter how small!- to this thread.
It would also be helpful to add some basic info about your set-up (size, filtration etc) to give people starting out an idea of what they will need.
Galaxy Rasbora care infoThis will later be made into a caresheet when we know a bit more about them! For now, it can be edited until we get it right
Latin name: This fish has now been officially named Celestichthys margaritatus
Common names: Galaxy rasbora, firework rasbora, celestial pearl danio
Category: Tropical
Difficulty: Pretty easy.
Maximum size: Around 1" or 2.4cm
Minimum Tank Volume: At least 8 gallons/35 litres for a small shoal.
Minimum Tank Size: At least 18" as they are quite lively.
Water pH Range: It has been reported in PFK that they prefer slightly alkaline water of around 7.3.
Water Temperature Range: Thought to prefer a temp of around 24C or less (as reported in PFK)
Water Hardness Range: Thought to prefer a GH of around 7 (as reported in PFK)
General Information: These are small shoaling fish that prefer to be in a group. The males do show some territorialism towards each other but don't generally harm each other.
Diet Requirements: They have very small mouths so should be fed small food! Frozen cyclops are being accepted. Live food is preferred, I have been feeding mine small daphnia and mosquito larva.
Compatability: Should be kept in a species tank for successful breeding. Their size means they should not be kept with anything large enough to eat them.
Recommendations: PLEASE please please do not buy this fish unless you have the facilities, time, money, patience and knowledge to breed them!! They are already at risk just 6 months after being discovered.
Common Problems: None reported yet.
Similar Species: Other danios.
Sexing: Fairly easy, the males are more brightly coloured. The females do not have a coloured pelvic fin and have a black spot on their vent when gravid.
Breeding: It has been achieved in captivity but little is known yet. Spawning mops and java moss may be used as spawning materials.
