A Hint Of Red?

[kpintheshed]

i took some pic but the tetra was so fast it dodges it or smudges the pic. its not a big deal but the top fin had a little half strip of red, but the other two dont. its acting fine moving keeps with the other two, eats. but its very hard to see the redish strip, do they have it normally because on the botton of my 3 tetras they have a white stip on the bottom. but theres no disease or anything.

i was going to says the other two tetras might get it.

i clean the entire tank every week or half. water changes Thur and Sunday. so the tank is clean the water quality's good.
