Brackish Water Fishincludes the archer, puffer, scats, monos and leaf fish
In their natural environment, Brackish Water Fish live where freshwater meets saltwater. In your aquarium a mixture of saltwater and freshwater is used. Brackish Water Fish are easy to feed and can readily adapt to various water conditions.
A well-balanced Brackish Water diet consists of:
- Live or frozen foods, such as brine shrimp or bloodworms.
- Flake and dried foods or vegetable matter.
- Some are scavengers and will eat any leftover food or debris.
Things to remember when feeding your brackish water fish:
- Depending on species, feed small amounts up to three times a day, no more than fish will eat in 3-5 minutes.
- Thaw frozen food before feeding.
- Keep in an appropriate size aquarium; provide plenty of plants, rocks or decor for hiding places.
- Stable water quality, water temperature, and pH levels are critical to the health of the aquatic life. If you are unsure of your water quality or pH levels, Petco provides free water testing.
