Hey, thanks for replies.

He's looking chirpier today. Maybe he was just resting.

They're in a split tank, side by side. They mirror each other's movements.

I'm also thinking it's a water temperature problem although I see the blue/teal one is making more bubbles so maybe he's just annoyed that he couldn't mate (or something). No chance of that with a male in the other side of the tank and no females in sight.

I changed 1/3 of the water yesterday and cleaned the pebbles and so I'll just wait and see.

If they didn't live alone they'd kill each other I think, Doody. LOL
