Thanks for the advice all. I will be putting Jake into his permanate 20 gal tank in about a week he is eating fine now still skittish but part of that is he is still in his quarnteen tank in a room that I'm the only one that goes in so it is quiet most of the time so when he hears much noise he heads for his hide. I did pick him up for about 45 seconds then put him back as he wasn't held alot growing up so I have to be patient in getting him used to it.
I leave a 1 cm gap on the sides against the glass, and stuff rolled up paper towel into the gap to avoid them getting their leg or toes caught in there.
