white tip fins

[studioskim3]

what does it mean when pletoral (?) the two bottom fins right below his chin, starts to have a white tip... is this the bone of the fins or what? this happens to most of my bettas... what does it mean? thank you!

Both of my betta's also have this. They both have fin rot too. I'm assuming it's part of the fin rot, but I'm not sure. I'm treating them with salt, and extremely clean water.

its interesting.... most or all of my bettas had the white tips... and all of them have or had fin rot too... but i think its cuz of the water... I had one betta who had the white tip, but never had fin rot... he died however b/c of something... is this natual?
