well i was in the pet store the other day and i had had a few deaths in my tank( 1 gold dust mollie 2 koi swordtail) and those deaths were very random because they didnt show in sign of sickness or death. but while at the store i decided to get a few guppys and some more hornwort. well i got three guppys 1 male and two females. on the way home i get too lookin at one of the females and she looks like she was born with a defect because starting at her anal fin she curves up and down like a wave. anyone know what happened? and since the females are both pregnant(like all guppys) will her babys be deformed too? thank for help
