double/triple mantis shrimp setup

[dunl]

Does anyone have any ideas on how to mod a 20g tank into a double or triple compartment mantis shrimp setup, running only one filtration system, but not allowing the mantis to actually attack one another?

Acrylic braces siliconed in to devide the tank into 3. Drill a few holes into each piece to allow water flow through each section. Make sure the holes are small enough so the mantis's can't get through.

Thanks for the reply.

Well, not much has happened, and not the greatest pics. Basically, I bought the cheapest piece of acrylic I could find, and glued it to the glass walls after drilling. Even if the silicone doesn't stick to the acrylic, sticking to the glass will keep the divider from moving, and it doesn't need to be incredibly strong with smaller mantis.

The drilling....first time, so made a few cracks. Basically, having a very fast drill and not letting it drop through the sheet is the key to drilling.

Some bad pics, lots of cleaning to do, but enjoy:
