Do not add any new tortoise to your existing collection without a quarantine period - 6 months is the minimum recommended. Your new tortoise may have had RNS or some other bacterial, mycoplasmic or even viral disease and may now be a carrier. There is no way of identifying a carrier with any certainty. Avoid stress - dogs or other animals worrying your tortoise, overcrowding, competition/aggression from other tortoises, or children allowed to play with the animal is stressful.
