Glow Light Tetras

[mezrie]

I recently have been discussing with Wilder the appearance of white outlines on the fins of our glow light tetras. For a while now i thought there could be something wrong, an infection or the like but it appears that this is normal and occurs a lot with these tetras. I've scanned the web and quite a few pics show this white outline whilst others do not. I was just wondering if anyone knows why some have these markings and some do not?

Interesting to read responses!

Common and perfectly normal markings. Tends to develop more with age.

Thank you very much

they come and go on my glolites so it's probably normal

The white marks are on all five of my glowlights.

my girlfriends glowlights get darker sometimes, does anyone know what this is?

I thought it might be the water quality?

Some of mine have it some don't - could it be a difference between the genders?

I have 12 glowlights,it appears to me that only the domenate males have these white markings,or atleast the males that are.....ummm...trying to impress and court the females.Could be wrong,but over a year of observeing them this is what it seams to me.

I have the same thing happening on some of my glowlights.
I had some green flame tetra in a different tank, one of them developed white edges on his fins. I read that this appeared only on males. Dunno if it could be the same thing as they both belong to the tetra family??
