Any advise would be perfect I jus don't want my little guy to die  

Answer
Hello Chris,

Is your male housed separately?
What is your setup like, currently?  What type of lighting are you using for him?  Can you post a picture of him for me?
If he is losing weight, then I would suspect parasites or worms.  A fecal should be done to rule that out though, as it can affect his health if his levels are too high.
Is he eating anything right now?
