I bought frozen daphnia for my betta's today, and i tried to dissolve a little bit in water. When they dissolved, they were just tiny brown dots. How do you feed them to the bettas?

Sounds like you did it right. Daphnia ARE just little brown dots.

Get an eyedropper or baby medicine oral administrator (the latter is what I use) and squeeze up some of the daphnia in their water, then squirt it into the tank. I give it to my Betta fry when they're big enough to eat it, but my older Bettas like it once they realize it's food.

Makesure soak them in aged water. Not straight from the tap water. :) If you got a brine shrimp net, used that to drain out the water.:) You can used a paper towel to drain too.:)

thank you everyone. I will do that!

i feed blood worms and i put them in the microwave to dethaugh then i use tweezers it feed them

I buy my frozen daphnia in cube form (Hikari). Then I put a little dish of hot water out and just cut one cube away, then set it in the dish to defrost. Then I use these little bamboo type of forks (with only 2 prong things) and i scoop a tad bit out and drop it into the water - that way it sorta sticks together in a ball.

The girls love it when it blows apart and it looks like it's snowing in their tank from their filter. It keeps them busin for hours :)
