Breeding Report: Rivulus ornatus
Location code: pucallpa '01
Water conditions: Neutral, 20-23oC
Spawning Method: Other (see below)
Breeding problems: Poor egg survival
Sex ratio: Almost all males
Breeding difficulty: Average
Success: Average
Other Comments: parents and eggs are sensative to pollution. Eggs are best picked from strands of java moss. breed in rather shallow water <2 inches. Very soft neutral water is used for maintenance. Large cool water changes will induce spawning behavior. 3 different forms have been kept with varying results. Padre island, pebas, and pucallpa(often referred to as speciosus but unlikely) Pebas is by far the prettiest form I have seen of the fish and more difficult to produce.
