i picked up 9 glowlight tetras on saturday. half of them look kind of pale while the other half look quite vibrant and actually really pretty. all of them have very red gills. there are two or three with gills that are actually exposed. not sure why, but they seem to be getting picked on a little by the other tetras, too. they all eat great and have gotten quite comfortable in the past couple days. we put a little air stone in this morning for a little more current and they seem to have calmed down a bit, not as much chasing going on, but still a little. got a couple pics of the exposed red gills but they are still kinda blurry:
