I have been trying to breed these fish for 2 years with no luck.
I have 7 fish: 4 males, 3 females.
They are in a 20g tall with natural gravel bottom and directed flow from the filter.
There is a stack of sand stones from their native stream I hoped they would spawn on. From the little info I can gather, they are "crevice spawners".
The males color up greatly and exhibit spawning behavior but I haven't found any eggs or fry. I assume they are eating them?
The females can get beat up sometimes so I have to separate them.
On top of the sand stones, I've tried putting in lots of java moss.
I've tried putting in a glass plate filled with rocks for them to spawn over in case they are egg scatterers.
If anyone has information, or knows where I could find it, I would greatly appreciate it.
Would there be any info in American Aquarium Fishes by Robert J. Goldstein? I can't find anything online.
