Well, you've all been tagging along with my observation of it's heavy breathing..
came home yesterday, and he seemed fine.. was chilling, breathing like normal.
Went back to check on him a few hours later, and he was in the corner of the tank, still breathing fine and seemed again, normal.
Went into the second portion of the fish room, came back like 3 mins later- noticed he wasn't breathing, and was stiff.
I pulled him out of the tank- and it kinda looked like he had septicimia, and I've dealt with that before from getting fish kept in bad water conditions for too long, and then the different water quality is just too much..
I don't really know what exactly killed the little guy.
I've never had any fish die from my water parameters- and I always prepare for a fish before I get one..
The only thing I can assume is that it was a mixture of my water, the sellers water, and the stress/trip all rolled into one.
