That's exactly what I'm thinking. Could've been my dog maybe. All other fish in the tank are ok, he's in with 5 bichir that are the same size but thinner, odoe, and a curu both being larger. The curu could've maybe gave a little chase and he hit something. Or he gets into quick squirmishes with the odoe sometimes, maybe he tried to bite him and it didn't work out well. I just got home from school so I'm gonna put him in a bucket to try and take a closer look at him. I hope it's only dislocated, I really like this mala, he has developed a nice green sheen and his fins have a slight red hue. And he's usually in the vertical striped pattern, unlike a lot of malas that usually have the thick bar going across. If it's broke, there's no way he'd be able to survive I assume? If it's dislocated how would I go about putting it back and will this start happening often now that it's happened once?
