Campellolebias intermedius, Costa & Deluca, 2006


Campellolebias intermedius is only known by the description so far. The species was found by De Luca A.C. et al. in 2002 on Oktober 27.

The place of discovery is situated 6 km west of Juquia in the rio Juquia drainage, rio Ribeira de Iguape basin, Estado Sao Paulo, southeastern Brasil.

Breeding Campellolebias intermedius is for hobbists with some experience and results vary. The species lives in primary forest , does not like to much light and should be kept in low pH values as low as 5 to 5.5 pH. Dark brown water and shelter for the females that are in the breeding setup with one male only. Males can be very agressive to other males but to females also. Eggs are fertilized internally by the use of an gonopodium which is characteristic for the four known species of this genus. As real annuals they live in temporary stagnant water near rivers.
After some days the female drops there eggs freely just above the bottom and these eggs need about 8 - 12 weeks to develop at a storage temperature of about 25 C.. Water temperatures for the fishes should be not to high and can be as low as 18 C. and as high as 28 C. (the latter for short periods).


High temperatures are shortening their lifespan that normally can be one year or less. Growth is very rapidly and reproduction starts at 2 months from day of birth if fed regulary with life artemia and other small life food. Dry food or frozen food is hardly accepted. Eggs are coloured deep dark brown, have short spine-like non- adhesive filaments on their membranes (Chorion) and are extremely hard to find in the brown peat.

Herve Gonin, France, reported his breeding experience about this species to us. He wrote: Camp. intermedius is an easy fish to keep once adult but the fry is fragile and does not like the change in water parameters. Incubation is 2.5 months at 25/26 °C. , sex ratio is quite good. Thank you Herve.
