Average success

Breeding Report: Scriptaphyosemion schmitti
Water conditions: Moderately soft and acidic, 20-23oC
Spawning Method: Spawning Mops
Breeding problems: Poor egg survival
Sex ratio: Roughly equal
Breeding difficulty: Average
Success: Average
Other Comments: Not really prolific, but best results obtained by leaving the fry to grow on with the parent fish. I experienced a problem with fungussed eggs whenever I collected them from the mops. I now leave mops in with the parents. I found that spawning would stop if other species were introduced to the tank, e.g.. Ep. dageti, A. occelatum, Cherry Barbs, etc. In my experience these fish are best kept in a specimen tank with a breeding team of 4/6 fish in 18"x12"x12". Males will spar occasionally, but I've only experienced minor damage from these squabbles. I use rainwater - pH 6.0 and low hardness. Temp around 22C. Egg production stops for me if temperature 24C. This fish is always slender, and will not gorge on excessive food offerings. Keep them keen by missing a day's feeding every now and then. These fish have been regulars at recent BKA auctions, and the quality of the strain of these fish has been excellent. Sizes appear to be being maintained well in subsequent generations judging from the Lots being seen.
