HEEEELLLLPPPPP 
i bought a little irwini about couple weeks ago. seemed fine for his first week living in my tank, but one day I got back home from work almost midnight..so I didn't give them food.
and the next day when I poured frozen worm to the tank..he just stood still..didn't eat it nor even touch the worm
and now...he's just like paralyzed...his fins doesn't move but his tail does. still breathing properly and still give me some reaction when I knock the tank.
can someone please explain what happen to my baby irwini??? or maybe I should do the water change??
thanks for ur explaination
