You want it to be pretty still in there. I use just an airline clipped to the side with a small suction cup, with the hose knotted so you get like a bubble every other second max. You can increase it as they get older and gain better control of themselves.
Also, in regards to their labyrinth, it's actually very cool to watch the day they get it. When the first one gets brave enough to take a gulp of air it reacts almost the way we do when we get water up our noses, kinda like it burns and "what the heck?! ouch!" and you can literally see the bubble behind their eye. Then the rest get curious and follow suit.
