A day ago one of my large Colombian sharks became spooked and rammed into my dwarf moray. I'm worried the shark may have broken the morays back. The moray used to hide in a very large stump entangled in the roots but now it lays lethargically around the tank on its back or stomach. Is a recovery from this even possible or should I euthanize it. I don't know what I should do. I've had it for two years and it has been my favorite pet. Sorry this was my first post on here.
