That is also a good idea, moving the parents is less harmfull and stressfull for all of us , for me and fish

Instead of chasing small fry, just pick up the parents with their shells...

The tank size where I keep them is also approx 10g...I still have no idea how many fry do I have, I have some problem with water temperature is about 25C...something is wrong with heater i must purchase new one today...
Is 25C (77F) OK for them?
