NORMAL BEHAVIOR & INTERACTION

Freshwater Sharks get very large in size so most are not recommended for the beginner aquarist as many will need a 300 gallon or more aquarium at adult size. Freshwater Shark species have a wide variety of temperaments from aggressive to peaceful and even the peaceful ones may eat smaller tank mates due to their large size. Freshwater Sharks should only be kept with similar sized fish. Some species like Rainbow Sharks need to be kept alone due to territory aggression while others can be kept in pairs. If your shark is a bottom dwelling species, do not house with other bottom dwellers.

FEEDING

Offer your Freshwater Sharks sinking shrimp pellets, appropriately sized tropical fish pellets, or frozen or freeze-dried insect larvae or brine shrimp daily. Some Freshwater Sharks will even eat vegetables! Most aquariums should be offered food twice a day in a quantity that can be completely consumed by its inhabitants within 1-2 minutes. Left over foods should be removed from the aquarium to avoid rotting. Stock level and types of species may require adjustments to these feeding recommendations. 

SUPPLEMENTS

While supplements are not usually needed for Freshwater Sharks if they are fed a varied diet, a lot of research has been done to suggest giving Vitamin C to a fish helps in disease prevention and healing.

ENVIRONMENT

The most important factor in a Freshwater Sharks environment is space. Sharks kept in aquariums to small will have stunted growth issues and usually die prematurely due to this. Multiple hide spots should be available for your shark. Sharks do all have in common a sensitivity to dirty tanks, so weekly water changes are usually recommended.

ACCLIMATING & QUARANTINING NEW FISH

We recommend water acclamation and 24 hours of quarantine (if possible) for your new Freshwater Fish. To achieve this float the bag containing the new fish in your aquarium for 10 to 15 minutes to equalize temperatures. At this point you can add small amounts of your tank water to the fish bag every 15 minutes or so 3-4 times. At this point, catch your new fish out of the bag and release it into your quarantine aquarium.

RECOMMENDED SUPPLIES

• Tropical pellet or sinking shrimp pelleted foods 
• Frozen or freeze-dried insect larvae or brine shrimp 
• Aquarium décor to provide hide spots
