Pacman swimming

[Samalander]

Here's a video of my old (got him in 1991) pacman having a swim in his freshly refurbished home. I just moved him from a 27-gallon to this 33-gallon. This is the same land/water configuration I've used since day one, the only variation being the substrate(s). In this revision there's an under-gravel filter plate with a drainage layer of river rocks. On top of that is a coir/sand mix to which I'll add another layer of worm castings (and plants) once he's settled in.
The pump creates a swirling current for him to swim against... I like to think of it as a hamster wheel for frogs!
