DG, Weaher loaches are intended for cold water, however if you acclimatise them to trop.waters you cannot return them back to the cold, they WILL die. Coolie/Khulli loaches and weather loaches are different. The coolie are trop.water only. They are much smaller and are black and yellow banded. Weather loaches can tolerate being out of water for a little while- I don't know about 3 days!!!
