Koi Treats and Snacks- Like other animals, Koi delight in treats, and will respond in a playful manner to them.
Koi Fish Treats drive Koi crazy. Koi love them. Koi fish treats should be fed only when water temperatures are above 50º F.
Fed in abundance, the proteins in Silkworm pupae can accumulate a good bit of nitrogen (ammonia) in the water so please check Ammonias if you're going crazy with Silkworm pupae.
