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.
