hey guys yesterday morning (wed) i received my bts it was couriored from wales to scotland and obviously came to me very stressed i know i havent had it long but i have some questions

it wont eat anything apart from cat food

it sleeps all the time hardfly moves at all in the tank even when you try move it about its just like moving a dead animal but its not lol

when i take it out the tank it keeps one eye shut and one open then just sleeps where ever i put it doesnt move

it also hisses a lot its fine in my hand but if i move my fingers or touch its back it goes nuts with the hissing

its about 2 years old

does anyone know what the problem is
