I recently wrote something for the BCA that lists references for all of the dwarf cichlasomines, including Ivanacara adoketa (not Nannacara anymore). I don't know when it will be published. Until then look up the fish under its new genus. There are many articles on the fish in several German pubs. and in the books Cichlid Atlas 1 & 2.
Hi Mike, your writings very much appreciated, the latest issue of Cichlidae (The British cichlid association Journal) has just been delivered and your articles excellent.. Long may it continue.
