I sold the atropersonatus and sterbai before I had a chance to try with them properly. One of them spawned but I'm not sure which.Wow, they really are small.
Great news with the fry. Are there any species in your collection you haven’t managed to spawn yet?
Other than that I've spawned all of the others this year.
If I get more room I'd like to try Robineae next as there doesn't seem to be many reports of them spawning in captivity. Also interested in trying Nannoptopoma sp. peru.
