Can my axolotl live on frozen blood worms only?

[Boomsloth]

so, what about crawdads? would that work as a good food source?
that is something that is plentiful for me here in Texas...

I do plan to start a worm farm myself and I will also be getting the salmon pellets as a backup food source as it is better than prawns

The crawdads you are referring too are definitely too big as adults and can do damage to your axolotls. If you are picking them up from the wild they can be carrying disease and parasites. I tried to breed crayfish (not as a food source) and found it more difficult setting up their requirements than my axolotl tank. They need to be sexed and have enough space an cover otherwise they will fight to the death. If you want a better freshwater crustacean option, go with red cherry shrimp. They will cost a little more initially but will breed like crazy and can provide a good supply of food.
