No way should you put 1.4 tokays in a 35 gallon. I have a pair in a 100ish gallon case and they use every inch of it. I would almost not recomend keeping more than pairs together females can and will fight. Sure you might get lucky and have a compatible trio but for the most part that is unlikely. As for anything other than tokays I keep cochroaches with my tokays for about 10 minutes at a time they don't seem to do to well. I figure anything else would fair the same.

Kevin your killing me with those tokays of yours.
Oh and while you can tame down a tokay you have to start with fresh hatchlings and handle them daily. I have succesfully tamed down a wc but it involved alot of blood before he realized biting me doesn't do anygood.
