I like to clean my tank (ten gallons) out every sat/sun, and normally anything I read, or ask people say

"50/50 tank!"

"One side water, the other rocks!"

But I how I have it arranged is the filter is in the middle, a small pool around it, a slow slope on either side, flat rocks scattered around, two 'long' plants drape in the water, and there's three smaller plants around all this. I've tried re-arranging to fit the ideal...

But all three of them seem to prefer the water (one loves it under the filter, he sits there and lets the 'waterfall' go over his back.) I've re-arranged four times, and they seem the happiest when I put more water, and in the middle. Should I go with what makes them happy, or the 50/50? (should be a no brainer but I don't know if the 50/50 is for health.)
