Diet & Feeding
The GloFish® Yellow Cory is an omnivore that thrives on sinking pellets, wafers, and a varied diet. Supplement with frozen or live foods such as bloodworms and brine shrimp for the best color and health. Because they feed at the bottom, be sure food reaches the substrate.
Tank Mates
Peaceful and community-friendly, GloFish® Yellow Cory pair well with other GloFish®, tetras, danios, rasboras, livebearers, and other small, non-aggressive species. Keep them in groups for the most natural behavior. Avoid large or aggressive tank mates.
Care Notes
Provide a soft sand or smooth gravel substrate to protect their delicate barbels. A well-cycled, filtered tank with stable parameters and gentle current keeps these catfish healthy and active. As with all fish, acclimate slowly when introducing them to a new aquarium.
