So, I have a 4-inch RES. He is currently in a 20 gallon tank. I plan on getting him a larger one. However, something has me worried: he doesn't really move around much. Never has. I've seen him swim for food and walk around on dry ground, so he's not injured. But he really only does two things:
1. sit on the floor under his floating basking dock. This is a corner dock, held on by suction cups. It has a ramp on either side leading up to it. (I also built a ramp with bricks--securely placed). So he sits on the bottom under that or
2. floats under it, sometimes scratching at it, or just sticking his head out of water--under the floating ramp.
I begin to wonder--why get a bigger tank when he NEVER leaves this corner of the tank? I intentionally aimed his filter so that his food floats away from this corner. He swims out, gets it, and swims back under. All day. He also never basks. Just hangs out under the ramp.
Advice? suggestions?
