Spider health

It is very important to be able to distinguish the difference between a healthy tarantula and an unhealthy tarantula. They normally live healthy lives if looked after properly, but get to know your spider and if anything does start to deteriorate you'll soon notice.

Most people panic when they find their spider lying on his back — but fear not, this is when he is about to start moulting. If you tarantula had died, you would find him laying with his legs curled up beneath him. 

Always pay close attention to the activity levels of your tarantula, keep an eye on the amount of food he will eat, and check his general appearance. Any changes in these could well be possible signs of illness. Be sure not to confuse any signs with those that happen before moulting.

A healthy tarantula should walk on the tip of his toes, if you see him walking down on his heel on a flat foot then that could be a sign of ill health. Any change in the appearance of your spiders abdomen can also be a clear sign of illness, so make sure it doesn't get smaller or become wrinkly as this is a sign of dehydration. 

Bleeding or unusual fluids could be a sign of injury, and are not to be ignored. 

A healthy tarantula should:

  • Have a healthy exoskeleton
  • Eat regularly when he's not moulting
  • Be active and alert.

If you keep your spider well fed, with fresh water each day in his bowl, keep his home clean, and maintain a good temperature in his enclosure, he should live a healthy and happy life.
