Hey guys! I got a fish from petco yesterday. It was donated because the previous owner could no longer take care of it. It’s in a QT tank at the moment and I’ve noticed it twitches every now and then. Like you ever get a chill go down your spine? Like that. That’s the best I can describe it. It’s not very active. It mostly just hides until it thinks no one is looking. Any guesses as to what I should treat it for? I also think it may have a bacterial finnrot. Not for certain though.
