I'm still trying for tankmates for my silver aro, but he keeps eating fish he isn't theoretically supposed to eat. (Then he glares at me cause he's lonely. ) I'm considering a Ray. So, a question to those of you that have rays: What is their temperment towards human counterparts in captivity? My only experience with rays was being aggressively attacked and bitten by a large wild one swimming in Tahiti. I'm a good swimmer but he had a hold on me and was so strong in the water that I came up for air when we came to the surface, but I realized it wasn't letting go, so my feet hit a sandbar and I ripped my hand out of his mouth and it was hard to do. It was a bloody mess or drowning. I just have some scars but that was better than Disney's Tower of Terror! I believe he thought I was food. But I don't know this species well enough to understand them.
