Hi and welcome,
Different species shouldn't be housed together because they have different needs and differnet pathogens so can make each other very ill.
Also please be aware that torts should never be kept in pairs - even male and female of the same species. They are territorial and it will be very stressful for them in a small enclosure where they can't avoid each other. They don't like or need a friend. From a young age one will become dominant and will bully the other. It starts with staring, hogging the food, following, nudging (mistakenly thought of as being affectionate). It eventually becomes more aggressive with barging, trying to tip over, and biting which can cause serious injury and even death. So to avoid expensive vet bills and suffering for your torts and to help them thrive it would be better to set them up in their own enclosures with their own sets of lamps etc.
You have a Russian tortoise and an Eastern box turtle, as was said above. Please set each up in his own environment, for their health and safety. You should also be aware that Connecticut has some pretty strict laws about keeping the Eastern box turtle.
