Food issue for CFBN larvae!?

Help!
During december i bought a few CFBN and now one of them have started to lay eggs, and i found some harched larvaes in the aquaria but i dont know really what how to feed them!?
Here is what i got as food options

•Mealworms (very much to big But might work with just the organs?)
•Frozen daphnia, But im not sure how to feed it .
•living fruit flies and/or bean bugs, only organs then i guess.
•pond water from the pond in My garden, i dont got Any daphnia net and im not sure how much life there is since its still a bit ice on it and that it have been a harsch winter.
•frozen red mosquito larvae, they are in a very good size.
•wild insects if i can find Any in the garden forest.

That is kind of it and i would love to have some tips on what/how to feed them and Any tips you got on raising CFBN larvae and eggs!

Congratulations
This will help Caudata Culture Articles - Raising Newts and Salamanders from Eggs

thank you any tips and so is still appreciated however !
especially of how to feed frozen food/daphnia

Once the pond thaws you can use a piece of thin cloth as a filter and run pond water through that. You will be able to get even the smallest organisms and you won't have to buy a net. Works very well for getting adequate sized foods for tiny larvae.

nice!
i tried it buyt it didn't work yet
well i were out before and took up some leaves and some algae in separate containers, hopefully i can get some daphnia from at least one of them.
i also used the time to catch some insects with live in the pond and gave them to my grown up CFBN as a little treat.

i would recommend but some brine shrimp eggs off ebay its good just to have them in waiting, i really need some too haha

haha well im actually about to try to let the larvae live together with live daphnias in a aquaria so that they can eat at all times
