sick guppies

[dkpate]

Are you sure they're slits and not just see through finnage? My 2 guppies look like little sword tails because the bottom part of the fin is almost invisible.

yeah they're definately slits. i've read that this just happens but i just thought i best check it out though as i noticed slits on 3 of them at once!
everyone seems ok though and nobody has anymore slits so i presume it was just something that happened... just trying to not stress them out at the moment as im making some changes to their tank and don't want to do too much at once...
