Campellolebias brucei, (Vaz-Ferreira & Sierra, 1974)

History

On November 28 1972, Gilberto Campello Brasil discovered this species for the first time between Criciuma and Tubarao (road BR 101 near road to rincao, subseq.) Estado de Santa Catariina, Brasil. The very same year Raul Vaz-Ferreiro visited the site again.

The american Ichtyologist Dr. Bruce J. Turner recieved specimen from the New and Rare Species Committee of the AKA.

He did send them to the describers who honored this by giving his name to this fish.

Reproduction

Breeding Campellolebias is for hobbyists with some experience, and results vary. The species lives in primary forest, does not like too 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 aggressive to other males but to females also. Eggs are fertilized internally by using a gonopodium, which is characteristic of this genus's four known species. As natural annuals, they live in temporary stagnant water near rivers.

After some days, the female drops their eggs freely just above the bottom. These eggs need about 8 - 12 weeks to develop at a storage temperature of about 24 C.. Water temperatures for the fishes should be not too high and can be as low as 18 C. and as high as 26 C. (the latter for short periods).

 

Eggs are small and often disappear in the peatmos, or in the Cocopeat that I use. I tried almost everything to produce enough eggs and I succeed in that but 95 % disappears within 2 to 4 weeks obviously due to false treatment or storage or bad fertilisation.

Remarks :

I am informed (by Dan Katz, USA.) the eggs need to be stored at low temperatures between 20 and 24 C°.
