abkMethod: Get a fresh xyz, wash it in tap water, cut it in tiny pieces , blanch it, and feed.
Xyz= Shrimp, fish, crab!
Thats my favorite diy food.
Cutting in tiny pieces is recommended.
Blanching is optional to get rid of any possible bacteria or such stuff. I do it since fish here are fresh caught and not frozen or treated.
Xyz=Pea, used to cure bloating. Remove the shell.
Xyz=garlic, 1 clove of garlic mix in water and add water to tank. Or cut in tiny pieces and feed. Use this rarely, once a month max. It boost immunity and appetite. No need to blanch the garlic clove.
Xyz= mosquito larve. I keep a small plastic box with water, has grown algae naturally and get mosquito larve once a week unless the sparrows get them first.. make sure to remove and feed larve once you see them else you will have mosquitoes flying.
Hope it Helps. Welcome.
