Just picked up a pair of "vents" recently and have them in a 10 gallon viv. My question is about feeding them. When they were in a smaller "starter tank" I observed them eating immediately. Now the 10 seems so huge I don't know if they're still as eager to eat because it's not so sudden as with the smaller tank. Is there any way of knowing that they are eating just the same? A bunch of fruit flies can get lost pretty easy in a ten.
