Many people enjoy keeping fish at home, and their aquariums often contain many small ornamental fish . However, many people are unsure how long small fish can survive without food. Let's find out.

How long can small fish live without being fed?

Small fish can survive for 7-21 days without food. Small tropical fish such as guppies, dwarf parrotfish, mollies, and zebra danios can all survive for 7 days without food. Small cold-water fish such as goldfish, ranchu, lionfish, and koi can survive for 14-21 days. These fish live in lower water temperatures, and their metabolism is slower.

What do small fish eat?

1. Live food

Small fish typically feed on plankton, aquatic plants, and benthic organisms in their natural environment, so providing live food is one way to meet their natural dietary needs. Common live foods include water fleas, water flea shrimp, water flea eggs, and water flea larvae. These foods are rich in protein, vitamins, and minerals, which help small fish grow healthily.

2. Frozen food

Frozen food is a common form of feed for small fish keepers, as freezing effectively preserves its nutrients. Common frozen foods include frozen worms, frozen earthworms, and frozen water fleas. These foods are not only rich in protein and fat, but also provide a variety of vitamins and minerals.

3. Dry foods

Dry food is the most common form of small fish food, and it usually comes in pellet, flake, or powder form. Common dry foods include fish food, dried insects, dried worms, and dried shrimp . These foods are not only easy to store and feed, but also meet the nutritional needs of small fish.

4. Artificial feed

Artificial feed is made from various raw materials through processing, resulting in a relatively balanced nutritional composition. It typically comes in the form of pelleted feed and powdered feed, and is suitable for large-scale farming of small fish. When purchasing, choose products with scientifically formulated and nutritionally balanced recipes, and avoid feeds containing excessive additives and preservatives.
