Splash: I have read info that goes both ways. Some say yes, others no way. Unfortunately I tried it. I wanted some kind of fish with the sharks, and went for a big lion. They did quite well together actually. I saw the lion snap at the sharks a few times when they got to close, but never thought this would happen.
I didn't give many details last night, but here's what happened. The lion did not purposely sting the shark. It was my fault. I was cleaning the overflows, and moving things around in the tank. I was also doing this at feeding time, and the sharks knew it. I left the room, and asked a friend to watch them while I cleaned the filters. I dint want the sharks to jump out while the top was open. My friend came running in saying one of the sharks was upside down. He said he saw the shark swim right into the lion, and then bolt away, running into the wall so hard he could hear it.
I stayed up most of the night with the shark. When he had trouble breathing, I tried to help. I had no idea if I was making things worse or not. But the bottom line is, the shark is alive!!
His breathing has returned to normal, gills are no longer white, and he's acting normal. The lion is here at work with me, getting ready to be traded at the lfs for shark food.
What Im concerned with now, is infection, and internal damage. Hopefully he'll make it through. Anyone have any suggestions for treatment? Antibiotics maybe?
