Gilima - The population from Gilima appeared in the UK as A.sp.Gilima (sometimes called A.christyi) in the early to mid 1980's. At first fry were reportedly hard to raise both in the UK & the USA. It would appear that raising the fry in rain water helped considerably.

Distinguishing Characteristics Can be very difficult to distinguish from A.decorsei. Both sp. are seperated geographically.
A.polli has few spots on body & unpaired fins. Red outer margins to dorsal & top/bottom of caudal fin.
Colour/Pattern Variability Low but spots on body & unpaired fins can vary in number.

A commercial import came in in 2004 which was distributed as A.sp.aff.polli CI 2004.

Spawns in soft / acid water similar to other members of the elegans group.

Diameter of Egg 1·2mm. Huber in Killi-Data refered to them as 'streaked'.
Remarks

Some authors question the validity & origins of this sp. Was it accidentally transplanted or is it naturally occurring? More work is needed. In the meantime I have put a page on the site for this sp.
