Everything you are doing sounds about right. The half land half water setup is great, but I don't think its worth the time and effort. I say this because I have probably only seen my frog in it's water dish once or twice, and I've had it for about 5 or 6 months now. I'm not saying its bad, I'm just saying it probably won't be used much. My frog only uses his water bowl for disposing of waste. So, to answer your main question, feeding. I'll just start by saying that I am by no means an expert, I'll just tell you what has worked for me. When my frog was younger, I would plop a plastic lid in front of it, and drop some vitamin dusted mealworms on it. Sometimes it would take a while for it to notice the worms, several minutes or so. So I would just make sure the mealies wouldn't crawl off (I used tongs because the frog would get less intimidated), and then just wait for the frog to strike. Sometimes I would unbury my frog then feed it. They do not suffer from froggy shock or anything, they just get kindof agitated. But after a few minutes, it would go from "Im angry" to "hey look, food!". I started with meal worms, then used large crickets. I would just drop 5 or 6 crickets in at a time, the frog would actually stalk the crickets. So...... yeah, thats basically what I did, hope it helps!
