I'm a bit late to this topic, but the tank I just got has 1/2" thick 3" × 1.5" "swivels held down by nylon screws (acrylic tank w/polycarbonate lids). Keeping fish in is a priority for sure.
I did not buy for this reason, but I do have a Nest camera pointed at the tank. I can view the tank anytime as long as there is home wifi. You could set on motion and sound sensor too. On my old tank I got my Lei jumping and hitting the glass lid late at night. It was on video (albeit dark since there was no light on the room). I believe the motion sensor alerted on my Nest phone app. It's not economical by any means but I enjoy the topic and my .02.
