Sorry just seen this. Yes he’s growing at about 1” every few weeks. He’s about 21” now
I got him in a 6ft tank and it took him a few weeks to settle again. He’s just started trying new food this week. For a few weeks we could only get him to eat haddock and he’d refuse anything else. He’s eating tilapia, whole mackerel, basa, prawns, loves squid and octopus which were new tastes this week.
I’ve just ordered a wooden pond for him to be made. It will take a few more weeks for me to get it lined and filter set up but he’ll be in a 7ft x 4ft x 4ft deep pond before October.
