While cleaning my tigers tank today i observed he had a pretty bad leg injury. it's on his back leg inner corner. it looks like it has been ripped/torn or bitten. i'm not sure if it's from his tank mate or if he got it hung on something. i put him in a critter keeper with wet paper towels. i'm worried about infection and healing. i've never dealt with an injury so i'm very worried and upset. he is still using the leg, it's still attached to his body, the wound is pink, not really red but i think i see a blood spot/sore. i'm not sure how long he has had it. i have about 20 dollars to my name so going to a vet is not an option for me right now 
. Please Reply with any information you have about injuries. I need to know how to treat it, keep it from getting infected, things to watch out for, etc
