Betta Fry Help

[bettanewbe]

Hi guys, so tthis is my first time breeding bettas and so far so good, ive had no apparent deaths and they are growing prety fast.
its been 3 weeks now and im noticing 2 of the fry are chasing the other fry. i dont know if its fighting but they are definately chasing them.
my question is should i separate them or is it still too eaerly...

Tank size? Number of fry? Decor? Can you sex them yet?

its a ten gallon tank, theres only 9 fry, theres just an air bubble filter and a small life plant (covers 1/10 of the tank), i dont think i can sex them yet... two are just chasing AND nipping the others...

A bit on the small side, but should be ok with that number of fry. Try adding enough plants that 1/2 the water is just plants? Otherwise you probably would have to separate the fish.
