30th July 2003. Colombia.
An unusual collection with a strange collection
history.
Collected by Steve McAlear in a recently cleared jungle area to make a road
to a butterfly farm.
The biotope was in two small pools ringed with small dykes. It was noted that
no spring or stream fed these pools & they were reliant on water from overhanging
vegetation from downpours. This area was previously under the forest canopy.
No aquatic vegetation were observed. The water lay on a sandy loam covered with
leaves. Fish could be observed jumping from this area.
Seven fish were collected from this area in a 500 ml pop bottle at 11 pm. These
were transported for 2 days on a river boat. Three fish survived which were
sent to the UK. On arrival one was dead but 2 females survived.
This was a remote area but we are hopeful of getting more fish in the future.
