Leave him alone for 2-3weeks?
Excuse me but I do not mean to mock, but what is this supposed to achieve exactly?
I have been visiting family and he's been all alone in his new viv for like 3days. He is still in the same position and has not moved a muscle. I know for a fact that he is alive because I just checked right now.
I think the best solution for now is to just sell him and start all over again. This is clearly a lost case no matter what I do and really, I do not have any more money to help him anymore.
