I just lost another one, but this time I saw it. One of the Pandas started doing "barrel rolls" before ending up upside down and sinking. I got the body out this time.
One Panda left and this one is pretty active and playful, the one that died has been sulking recently.
The dead Panda had nothing wrong with it. It's fin was fully black and I couldn't notice any spots. Two dead now, so Im worried about my tank. However the other fish are doing fine and the water seems okay.
Could it be a disease? Is it a food thing? (I mainly feed my fish flake food which the tetras get to first. This doesnt bother the otos at all.)
Here's my current stats
temp: 26-27 C
I had a little algae problem but a timer and the otos are on top of that now.
:edit: I realize Pandas a senstive to stress after just reading up on them. Also like to be in a group. If I want to save the last Panda, should I get new Panda to be it's mate or should I wait. How many Pandas is best (keep in mind I have a small tank).
