Is there any ways to make a fish fry grow bigger and faster?

Bernie if those are apisto fry, most males grow faster than females. After a certain size it would be best to separate larger ones from smaller ones, else you might end up with more males as they tend to out-compete smaller fry for food.

Coincidentally i am posting in another thread, let me "share" with you how to grow your fry fast and big in short time ( which i dont really recommend for apisto )

- feed them tubifex.

I increase the growth of my betta fry by first packing them with high protein food, be it pellets, frozen or live food, add in a submersible pump to create current, change water twice a day since my water would foul quicker due to the intense feeding, add a light and switch it on during the evening to prolong the impression of daylight and lastly include a heater to increase the temperature to boost metabolism. Please do not ask me what detrimental effects that such above mentioned actions would do to the fishes but I can the fishes reached its ideal size for competition back then in almost half the time as compare to normal fish keeping. But during this period, water quality must not only be good but tip top condition.

To grow up frys, i stick to my own 3 rules:

1) sufficent swimming space. if i got more than 80 apisto frys, i will split them up. the bigger one goes to one tank and the smaller one goes to another (2ft tank)

2) Filteration and water flow rate.

3) Type and availability of food


To bernie: with regard to those very small buggers, check to see if they are runts or just slow grower. Runts will have irregular scaling and usually comes with deform spinal. Those i will cull immediately. If do not have such symptoms, i will isolate those smaller ones in another tank. at times before of their bigger and more aggressive siblings, they do not have chance in grabbing food and do not dare to swim around openly. Thus stun growth.
