Lost my first Piranha due to cannibalism last night. I purposely don't feed them 2 days a week, usually sunday and wednsday, and last night I paid for it as they took out the smallest piranha in the group :/ Not that I didn't expect it because honestly I expected to have lost more to cannibalism by now than just the one. I was going to post another feeding video but these damn powerheads keep falling off the wall and stirring up the sand like a nice pot of soup so the tank is cloudy again. Which reminds me, time to send a complaint to marineland on their **** "pro" powerheads. They used to be great I used them in my reef tank with the sure flo mods but now..... never again.
