What are your thoughts?????

I have 6 leopard geckos. A male bandit, male bell albino het. patternless, male giant SHTCTB, 2 female SHCTB's, and an unsexed murphys patternless. I had a job that required a lot of travel both in my home state and to other states so I had someone else care for them while I was gone. On the eighth of this month I had an injury at work that broke 2 fingers, tore tendons in my fingers, and tore a ligament in my thumb so im out of work for a while and ive been spending a lot of time with my reptiles as a way to ease my mind in this very very stressful time and ive noticed a few things that I need some opinions on. First I need some tips on how to get my stubborn bell albino to eat, I bought him at the Columbus reptile show back in February and hes never been a very enthusiastic eater, I usually have to hold him and irritate him to the point hes ready to bite and toss a mealworm in his mouth but hell only eat one or two if im lucky and when I got home i noticed he has lost weight. Its not enough to worry too much about yet but I want to nip this in the bud before it gets to that point. My next question is where do you guys get your 15-16qt tubs at? I'm housing my geckos in 12qt tubs right now and while ive been away my geckos have really grown with the exception of the bell and their ready to be moved to bigger tubs. Ive went to the local Walmart numerous times and cant find the right sized tubs and if I do their way too deep and not wide enough. Any info/advice would be greatly appreciated.
