Oh thank you for telling me i will either separate them or return one back and take care of the sick tortoiseThe above will help you get everything you need.I chose the title of this care sheet very carefully. Are there other ways to raise babies and care for adults? Yes. Yes there are, but those ways are not as good. What follows is the BEST way, according to 30 years of research and experimentation with hundreds of babies of many species. What is...tortoiseforum.org
Sand is not a good substrate because it can irritate skin and eyes and if ingested can cause the gut to become impacted which is very painful and can be fatal. The caresheet will advise you on what to get as well as lamps, diet etc. What you are feeding him is not good for him. So please read that carefully.
Your tort needs a secure enclosure (minimum 4 x 8 feet but the bigger the better ) and not be allowed to wander around a house. Things like cleaning chemicals,, dust, human hair and small hazards that could be swallowed are all dangerous for your tort. There have also been torts killed by getting crushed in doors.
You will need 2 enclosures and sets of lamps etc for 2 torts because they should never be kept in pairs.
Torts are solitary creatures and do not like or need friends. They find it very stressful having to share their space and that can cause illness and when the bullying starts (staring, following, nudging, barging, tipping or mounting and biting) it can cause serious injury and even death.
So please do not keep them together or they will have a pretty miserable life.
