how do I fatten up my betta fry, they are thin but long.?

Answer 1

How old are the fry? Betta fry takes a while to grow.
Here is some info about growth...

One week old: 0.2 inches long.

Two weeks old: 0.25 inches long. (Starting to show dorsal fins.)

Three weeks old: 0.34 inches long

Four weeks old: 0.45 inches long on average.

Five weeks old: 0.6 inches long. Size ranges from .5 to .75 inches.

Six weeks old: 0.85 inches long. The largest are over an inch.

Seven weeks old: 1.1 inches long.

Eight weeks old: 1.3 inches long.

Nine weeks old: 1.55 inches long.

Ten weeks old: 1.7 inches long

Eleven weeks old: 1.9 inches long

Now what to feed, I feed mine newly hatch baby brine shrimp less than 24 hours old, also Infusoria. And occasionally feed them First Bites powdered food.
Here is a list of other options to feed the fry:
Chopped frozen bloodworms, live or frozen daphnia, mysis shrimp, brine shrimp, shaved frozen krill, freeze-dried bloodworms, brine shrimp, and very small granules of HBH BettaBites or GuppyBites are good foods to use. Bettas fed good food twice daily and given good conditions will probably grow fast enough to start being reliably sexed at 6-8 weeks of age.

You must make sure that the water is also very clean and the temp stays in the same range. Also when the fry get bigger you need to seperate the larger ones from the smaller ones.


Hope that helps!

Answer 2

If you have access to tubiflex worm, get some and chop them up with a razor into 1 or 2 mm bits (depending on how big your flys are) and feed it to them.

If you have no access to TB try to look for daphnias and feed it to them.

The above two methods are the fastest way to do it, but they do mess up the water some. So more frequent water change is needed.

The other method you could use is to feed them new hatch baby brine shrimps. These are good when they are very young (2 ~ 20 days). But I find the above two method more effective after their 3 week.

When you look at a well fed fry, it stomach should be slightly bulging. That's the way I gauge if I fed them enough.

Lastly food isn't the only thing that ensure fast growth, clean and good environment @ a good temperature will also play a part in their growth.

Answer 3

How old are they? If they're more than a few days old, newly hatched brine shrimp would be good. Or you could see if anyone around you has microworm cultures (check if there's an aquarium club near where you live). The hard boiled egg yolk is okay, but you need to feed very small amounts.

Answer 4

I feed my jack dempsey fry bits of disolved hard boiled egg yolk, but it dirtys up the water quick.
