Regarding enclosure size, it would depend on the size of your T, it should be only twice or thrice its size... so if you have a 1 inch T, your enclosure should only be 2x2x2 or 3x3x3 inches coz if you'll provide a larger one, your t might have difficulty catching its prey...
Avoid feeders that are larger than the abdomen of your T especially on slings...

YOu may end up seeing a 1-peso feeder eating your 1.5k tarantula... hehehe... Recommended feeders are: Crickets (pinheads for slings), lateralis, mealworms...
