i got 3 fry from my friend and had them for three month now i learned tht they are diffrent gendders but there are black poka dots apearing and disapearing every hour why
This is exactly what is happening to my guppy fry! Especially one of them though. It gets some black on its tail and then its gone and then its back again.
My guess is that they are starting to get their color. This is only happening to my older fry that are one month old.
Good Luck, and Hope this Helps.
Never heard of that before!
