wild from the river itaya peru | | Water conditions: Neutral | Water temperature: 20-23oC | | Disposition: Active, but not aggresive | Community tank?: Only with species of similar size | | Spawning Method: Spawning Mops | Breeding problems: none | | Sex ratio: Roughly equal | Breeding difficulty: Average | | Sucess: Very unsucessful | Years Experience: | | Other Comments: Since these fish are in my possession for only 3 months I find them easy to care for in a 5 gallon aquarium for 3 pairs. The tank has a box filter, Java Moss and a floating mop where eggs are collected on and off during the week. The fry have to be forced hatched after 2 1/2 weeks by adding microworms in a pillbox with a vigorous shaking. The fry will eat newly hatched brine shrimp and later on flakes. They can be sexed after 2 months. | | Date this record created: 20th April 2003 | Breeding date: | | Breeder: Hans Behr | Location: Montreal Canada |
