Everything went well as I slowly got him acclimated to the warm 79* water. I put him in after about a half hour and he loved exploring his new home.
I then went to the bathroom for a few minutes and came back to check on him. HE HAD SQUEEZED BETWEEN THE DIVIDER AND THE TANK WALL!! I hadn't thought the tiny gap was big enough! But it was and he was gorging himself on the oto cats' chunk of algae wafer!
The pig is now bloated from eating too much! At least he got his veggies.
I'm putting him back in his 3 gallon tote with a 1 gallon dose of Epsom salt to help with his tummy. He's currently acclimating back to it right now.
