This is a discussion on White on end Fish Fins.....Is this an issue! within the Beginner Freshwater Aquarium forums, part of the Freshwater Fish and Aquariums category; -->
Sorry results were before water change. My temp in my tank only varies about 3 degrees at most! I have 2 100 watt heaters ...
-tetras also loose their color when the temperature of the water is too low. Bloodfins can survive in 'cold' water, but will loose their color
-some bloodfins do not have a red fin, but a translucent one
-bloodfins are verrrrrrrrry hardy
