- Frozen Foods
- cockle - feed to bigger fishes unless you chop it up,
- mussel - a bit messy, but smaller fishes will eat the scraps,
- gamma fish - whole fish for the larger inhabitant,
- shrimp
- brineshrimp - not very nutritious, however often a good food to wean picky feeders,
- mysis shrimp - more nutritious than brine, but the exoskeleton can be too hard for smaller fishes,
- gamma shrimp - similar size to the mysis shrimp, but with a much softer exoskeleton - a tasty treat,
- clam - some fishes need to acquire a taste for it.
- Dry Foods
- marine flake - a good food with added vitamins - feed occasionally
- dried marine algae and seaweeds - for all those herbivores, Tangs, Angels, Blennies etc., also accepted by many other fishes - even my Dwarf Lionfish (strange)
- Household Foods
- lettuce - place in boiling water for about 30 seconds to make it easy for your fish to eat
- spinach - another favorite for herbivorous fishes
- peas - accepted by many fishes
- prawns - fish love them - ensure that they're not seasoned if buying from a supermarket
The above list is not definitive - however it does show the variety of foods that can be offered. The combination of good water quality, plus a good feeding regime will provide you with healthy disease free livestock and many hours of pleasure from your aquarium inhabitants.
