Everybody gets three feedings of one 'Omega One Small' (<1.5mm) pellet per day. That's 3 pellets/day. I perform two 50% changes back to back every day; roughs out to 60%. I do it that way because the pH rises from 7.6 to around 8.2 between changes; I don't want to pH shock him.
He's in a bare-bottom tank, so I'm able to remove feces and food bits daily. I just figured the little glass-surfer was high-metabolism and a growing boy.
What's really got me stumped is the low rise in NH3 and pH in the divided, unfiltered 4g (gravel, rocks and plastic plants) compared to the 2g bare tank. Those two guys are moderately active, seems to me.
I understand that over-feeding is unhealthy --- fatty liver and obesity --- but I don't know how to tell if my fish are fat. I don't mind the water changes too much.
