hi all im new to breeding bettas i have currently 2 breeding pairs and without fail every 3 days there is new fry. I keep around 100 fry alive per spawn but i still lose a hell of alot of fry. I have got around a thousand fry at this moment and are all alive and well. there i have 2 lots at 3 weeks old 2 lots at 2 weeks old and 4 lots under 2 weeks old. Im looking for advise to increase the survival rate. I have now 8, 30lt tanks but cause im worried about losing fry to a filter im regually cleaning out the tanks and its a mission. Hope there is some people out there that can give me some advice and im sure i can help some people out with starting there betta breeding. But as i said i only know how to quickly breed them to get fry but any time after the first week i can only keep around 100 alive.
