How to feed Frogspawn?

[bigred]

I have 2 frogspawns and after the lights go out I can see their mouthes. Should I take a piece of food and put it in it? I have some shrimp prawns that I feed everything else, just break it into small pieces like I do for the fish?

you can try if you want but it's not really necessary. if you have sufficient enough lightning then you should be ok. they will feed off of the light and the elements such as calcium, etc.
