Lake Kutubu rainbowfish

Stocking Fish Tips: For new tanks, be sure the fish that you add to your tank are hardy. After the tank has aged for a few months, less hardy fish can be added. A tank needs to “mature” (complete the aquarium nitrogen cycle) before it can accomodate certain species of fish. Submitted by: Dahly
