I have a Port Jackson shark that acts died. It swims around then flops died. It does this all day long. It's been doing this for 2 months now. I watch my water quailty really close. When it flops died it lays on its back. Help keep sharky a live!!!!
I dont know much about Horn Sharks but they are not active swimmers and they need colder than normal water. I dont think the upside down part is normal unless it newly hatched.
