Foxface And Blue Hippo Sleep Together

I know that when the Foxface is scared or sleeping it goes into its camouflage mode, and the dorsal fins are venomous.

So I think it's a bit odd that my small Blue Hippo loves to wedge itself up right next to the Foxface at night.

Right now, the Hippo is below, but usually it almost lays on top of the Foxface.
I'm waiting for the Hippo to startle it and get "stabbed".
But I guess they enjoy sleeping next to each other...
There's a whole tank, and everyone sleeps next to the heater.

The Foxface is almost right up against the heater, it doesn't get too hot for it?

Weirdo fish

 

Too cute! My clowns sleep together under my overflow and my YWG sleeps in his home in the rock work.

I guess if he gets too hot he will move?

 

That's what my 2 clowns do as well...
I have a Emperor HOB filter for mechanical filtration and what not. And they lay on their sides right under the waterfall.

So when the level is a little low, they'll just get tossed up and down from the flow. It seems like not the best way to sleep

 

Cute....all my fish seem to sleep in the same corner as well...near to the heater.
