Freshwater Sharkincludes rainbow, redtail, bala, apollo, silvertip and black shark species
The generic term "Shark" is applied to many unrelated fish with a similar body shape found all over the world. Freshwater Sharks are not true sharks, but are typically catfish or relatives of carp. Freshwater Sharks add personality and character to an aquarium.
A well-balanced Freshwater Shark diet consists of:
- Flake, pellets or freeze dried foods.
- Live or frozen brine shrimp.
Things to remember when feeding your Freshwater Shark:
- Feed small amounts two to three times daily, no more than fish will eat in 3-5 minutes.
- Thaw frozen food before feeding.
- Keep in an appropriate size aquarium; provide plenty of space for swimming and 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.
- Some species, such as rainbows and red-tails, are territorial and should be kept individually in a community tank.
- Some species, such as balas, should be kept in schools of at least three Sharks of the same species.
Daily: check filter, water temperature and other equipment.
Weekly: check water quality at least once a week.
Monthly: change 10-25% of the total volume of water every 2-4 weeks, or as needed.
Introduce new inhabitants to the aquarium gradually.
Generally, Sharks are compatible with like sized fish of a similar temperament (community with community, semi-aggressive with semi-aggressive).
