definitely, i still have the feeding tank he refused a long time ago. probably because when i was trying it he was still new to me and a picky eater. now he eats f/t great for me with no problem every week. i'm just worried to try now since i am monitoring his habits so closely for the impaction. if i tried the feeding tank next week, i wouldn't know if he wasn't eating due to the tank, or a possible impaction problem. so maybe i'll just switch the substrate out for now, and implement the feeding tank later when i discover he's alright. thanks again.
