I haven't heard of health issues but it will cause pyramiding even with high humidity.Its been advised the MVB aren't good for any tort as it can lead to health issues.

They need over all warm temps maintained by a radiant heat panel or CHE controlled by a thermostat in a large closed chamber.is it safe to use a mercury vapor bulb for cherry heads
