I purchased 3 (thats all they had) rummy nose tetras last night from my LFS
. Their noses were pink not red and their tales were not a dark black checker.
It's about a half hour drive home, and by then they had no color at all.
This morning their noses were bright red and their tales had a good checker black and white.
Was this all stress. I really expected at least 1 to not make the night.
