Appropriate home: An aquarium with at least 29 gallons of water, an exterior power filter with a bio-wheel, a maximum of 1/4 inch of gravel, and an aquarium heater adjusted to a temperature between 78 and 82 degrees F.
Each Baby Whale needs its own cave or piece of plastic pipe as a home. Be sure the rocks or pieces of pipe and everything else you put in your aquarium will not contaminate the water.
Be sure their aquarium has a cover because Baby Whales are active jumpers. You should also cover all the holes in the cover.
Recommended Diet: Live Black Worms and other live foods such as live brine shrimp. Most Baby whales will also eat frozen brine shrimp.
Compatibility: One Baby Whale or several but not a few. If you keep 2, 3, or 4 Baby Whales together in the same aquarium, the strongest one will often make the others miserable. In a group with 6 or more the stronger Baby Whales become less aggressive.
Good tank mates for Baby Whales are Elephant Noses, African Black Knife Fish, and Synodontis Catfish. Baby whales are also kept in aquariums with Clown Loaches, Gouramis, and Angels.
Size and Life Span: These Baby Whales will grow slowly to be 8" long and can live for 6 to 10 years or sometimes even longer.
