Thumbnails in general are fairly active..........only a vast majority of them will duck and cover if they see you glaring in. THere are a few that are more bold than most tincs, like the D. imitators. I have heard standard lamasi are pretty bold as well. Then if you also start looking into the egg feeders such as pumilio, they are very bold (have you seen the pics of the male blue jeans taking on a full sized tinc??? ). And, like you say, it is never to early to start planning your next viv

Major rule of thumb though: the more hiding spots and vegetation you plant in your viv, the more active and more often you will see your frogs. If they always have somewhere they can dart into, then they will feel a lot more comfortable than only having one or two good spots to hide in. SO, if they have more hiding spots, in question, they will utilize more of the viv

. I have a group of vents in a VERY thick 75 gallon, and generally vents are very shy frogs. Mine are just as bold as my imitators though, and I contribute that to their vivarium and the way it is set up. Anyway, take care, and ask away, I am sur eothers will help answer
