Wow I just came across this thread! That tank is awesome! That really makes me tempted to do something like that for my Dubias.... I have a weird attachment to them lol. I've had the same adults since they were nymphs (almost a year!). So the other night when I ran out of crickets and needed to feed a couple nymphs I actually was a little sad to do it! My boyfriend had to remind me that I had them to use as feeders LOL. Thankfully it's going to be a while before I have enough to feed off of regularly haha. But I do have a spare 5g that I could soup up for a select few... It's tempting!
