They can get "wet tail" otherwise known as diarrhoea. It's very bad for them. You can notice when they have it by checking on their bathroom doings. If they are wet, they could have diarrhoea. If they are dry, that's a good sign. Avoid this sickness by buying them medicene to put in their water. You can get it at a local pet market.
