thing about snappers is generally they like to hang out in shallow water and stretch their necks up for air. but in creeks they generally hang out in undercuts. A 55 would be great for them, but if you fill it up, make sure there are plenty of shallow places they could hang out in like rocks, logs, or floating vegetation. I suppose plastic basking areas below the water level would work too. Heres one thing ive done, get plastic poultry netting from the hardware store, and hang it inside the tank on the walls. you could hang it with a number of things I imagine, i used stainless tig wire. If you use metal, make sure its stainless so it doesnt rust. I suppose suction cups might work too. That way the snappers can do the creek thing and just hang on the walls. And of course, feeding in a separate container is a good idea since these babies will shred anything they eat.
