I recently adopted an African Clawed Frog from a family friend and I have a few questions,

1) How high can a ACF jump out of water? Right now there is between 1.5-2in between the gap around the filter and the water.
2) Does the filter need to be on 24/7? Or can I turn it off while I sleep?
3) The tank came with AED lights, can these harm the frog? Or will he/she be fine with them on during the day and off during the night?
4) What time of the day should they be feed, or does it not matter?

I would gretaly appreciate it if someone can answer my questions.
