They are together. You couldn't see a happier gerbil than Honeybear. She just loves her new boyfriend. We put the wheel in the tank. HoneyBear missed her wheel. Buddy really didn't know what to make of it. He is two years old and never been on a wheel. Honeybear supervised and give tips on how to run. Honeybear is 3 years old. They are both past having babies. It is not 100% but the risk of babies is low.
