My B. juruense was spooked and slammed into the glass at s high speed a few days ago. since then it has been laying on its side. you can clearly see the swelling in the fishes head. has anyone seen a fish recover from a injury like this? its been a couple days and the fish is still breathing and occassionally moves around. the rest of the fish is normal in color. is it possible the fish has a concussion, brain swelling? any info. or experience would be appreciated.
