Two in one cage?

... They also should not be able to see one another.

I'm curious as to why this is; how damaging it could be... I've got my pacmans in adjacent translucent cages so they can share a heating element. Should I move them?

Pacmans can be very determined creatures. If they see another frog, they may try to go after it. Regardless of what triggers the reaction (breeding impulse, hunger, territorital assertion, etc.) I have heard many stories about pacs in clear, divided tanks either hopping over or sqeezing around the glass divider. I have also seen them go after their own reflection. They think it is another frog and will ram into the glass again and again, causing serious harm to themselves. You can't predict when this will happen; they may be kept together for months or even years before something triggers an agressive action. These frogs are not meant to cohabitate.

In your case, Surrealasm, you can place some sort of background on the glass not covered by the heating element. Then they will not be able to see each other; problem solved. It is a good idea to have three sides of the tank covered regardless. It reduces visual stress for them, and they feel more secure.
