That’s awesome, congrats! Happy you cracked the code so to speak.Well after months of worrying that my gigas wasn’t growing I think I’ve finally been able to make him happy. Only took 2 tanks and 3 light fixtures for him to start showing growth. Literally had no white on the shell for months. Tough to guage the scale in the picture but that white band is about 3/8-1/2 inch wide. He’s got a ways to go to catch up to some of the others but I’m just happy that he seems happy now
