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 this remarcable species is even for me as specialist in south american annuals not easy. In the first place it is not easy to obtain fishes or eggs from anyone, than the production of eggs, if succesful will not always give guarantee that offspring wil be available after the incubation time. My experience with this fish was a long struggle to have enough fry to keep the species in my collection.Seldom I had more than 2 or 3 males between the females that were plenty sometimes.

 

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 :

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