That's good news that he's showing aggression: I bet the improved water and food have perked him up. If he's eaten a lot today, I might let him fast or just feed one pellet tomorrow, to avoid stressing his system with too much too soon. Looks like you're doing a great job so far! :clap:
Yep, thats what I was planning! He's going to be a total pig when he gets to be a bib boy. He was grazing on leftover pellets at the bottom of his container!
Aw, the poor little guy. It's so sad when he flares but no fins to flare with. So great of you to rescue him, he's in good hands! Is Magnus his name? I love his colors.
