I heard you can feed your fish peas, along with some other veggies. How do you prepare the food and get it to the bottom for corys? What veggies do you feed your corys?
Mine like courgette, I blanche it for a couple of minutes to soften it slightly then weigh it down with a fork.
For peas just deshell them, squish them slightly & drop them in, only feed peas once a week as they act as a laxative
Please be aware Corys are 95% carnivores, in need for high protein food. They can and will vegs as well, but still main food needs to be other food !!! Other part I agree with Lillefishy.
