Good question, but not to my knowledge. I do, however, know that if you keep them in a regular aquarium, that they need an undergravel filter, to keep them from getting sucked up (HOB's dont work, because the output it too strong, even with the intake covered). They also need a blacklight, so you can view them, and blacklights are IMO, not safe in a regular fluorescent fixture, even though thats what they are. They run hotter, and again, imo, are a fire hazard.
