I came home from work today. Went to feed the fish. I noticed my 7"-8" African Pike was missing. I looked everywhere around the tank. My tank is "Arrowana Proof". I have no idea where the fish is. I looked for a good 30 mins or so. My only guess is that my dog heard him jump out and had it for lunch. Are these fish known for jumping? Will this have any advers affect on my dog?....Help please.
