the 4 survivors-later on i found 2 more. These tropical fish are used to 25 Celcious degrees water warmth succedded to survive in 14 Celcious for 5 days found by accident. they where small compared to their brothers in law at the main tank but healthy, living without food this all that period- amazing. to enter them inside the warm water i needed to add small portions of warm water from the main tank gradually inside their temporary container so their body will not get a shock, what called 'stress'.
