Unsuccessful

Breeding Report: Rachovia hummelincki
Water conditions: Neutral, 28oC+
Spawning Method: Peat (or similar) spawning substrate
Breeding problems: Deformities
Sex ratio: Somewhat female heavy
Breeding difficulty: Difficult
Success: Fairly unsuccessful
Other Comments: First attempt at breeding, all adults jumped out before spawning occurred. Keep a tight fitting lid, no substitution, floating plants do not suffice! Second attempt, no healthy males to breed, only male remaining is a belly slider. Very high percentage of belly sliders in this species. Suggest reducing the incubation time by half the recommended amount. If 27C then 1 month, no longer. They prefer high temperature, and eat a lot. Not picky eaters will take dry flak/prepared foods.
