AUGH! It wanted me to log in after I hit the submit button and didn't post my message. Gotta see if I can remember what I typed.
He was originally in a tank full of tetras. When we first got him he was quite active, he'd swim up and down the tank about 3 feet, it's a tall hex. A few months ago he started just hanging around at the top. The PH in the tank had gotten up nearly to 8 so I thought maybe he didn't like it and put him into the tank with the cichlids because its PH is around 7. They must be pretty unintimidating, they're geophaguses, severums, electric blue and yellows, silver sharks...Even the tiny little juvenile blue ram isn't intimidated. He seems to be getting enough to eat and has gotten more active in that tank. BUt he still just hangs around the top. I did notice yesterday that he swam an inch or so below the surface and then bobbed back up. Don't know if that was the current, intentional or if he's got something like a swim bladder problem.
I did try to breed him. Unfortunately we didn't get any eggs, they tried though. Don't know if the female was too old or what.
