|Danio albolineatus Blyth 1860
|Common Name:||Pearl Danio
|Scientific Name:||Danio albolineatus
|Origin:||Found over most of S.E.Asia.
|Size:||55mm (2¼ inches). S.L.
|Comments:||Another of the "standard" Danios. Has lovely "mother of pearl" colour in
natural daylight. A semi albino "gold" variety is also available and is common
in captivity. There have been a number of species which have been deemed to be
synonyms of D. albolineatus. These were generally colour morphs. Dr Martin
Brittan in his paper of 1955, described a species and named it after Mr M.W.F.
Tweedie, Director of the Raffles Museum & Library in Singapore. This was
Danio (Brachydanio) tweediei. Subsequently, it was deemed to be a synonym of D.
albolineatus. Recently, in a tank in a local fish shop, there were a number of
different coloured D. albolineatus. These were purchased by Paul Rowntree who
has since successfully bred them. Reference to Dr Brittan's paper indicates
that they are probably the previously named Danio tweediei. Paul has been in
contact with Dr Gerhard Ott in Germany. He and Dirk Dettmers caught D. tweediei
in Sumatra in 2003 and have successfully bred them in an garden pool each year.
They are of course housed inside during the winter months. Dr. Rainer Hoyer
from Leipzig, Germany has a F2 fry from Gerhard's F1. Preserved samples will be
sent to Dr Fang Kullander for her examination. The difference in colour
vis-a-vis albolineatus and tweediei is quite noticeable. It is of course
recognised that colour alone does not make a new species!
