Choose food for your fish

Compare the intended species, ingredients, food size and feeding behaviour on each listing. Herbivorous, omnivorous and carnivorous fish have different dietary needs, so one formulation is not a universal choice. Follow the manufacturer's feeding instructions and select a food format your fish can eat.

Aquasonic Tropical Water Conditioner is a salt-based aquarium additive, not fish food. Check its suitability for your livestock and water conditions, and follow the label directions before use. Feeding blocks are not a replacement for monitoring your aquarium while you are away.

The Cherry Spot Tropheus live-fish listing also appears in this collection and is marked no online purchases. Selected bulk foods are special-order items, and the 15 kg conditioner listing notes additional delivery charges. Check individual listings for purchasing and delivery details.
