They look fine! Eye to body looks right. Body looks right and round. You did good . Since they are young I’d be changing 50% or more water daily. Feed as often as you can. Feed good foods. What are they eating? Try freeze dried black worms. Can be bought from Al on this site. Vita-bites,sera discus bits,and good flake foods. I’ve got 3” guys now that are just eating the black worms now. 6+ times a day but I add the others just to get them used to them.
Keep them in the 30 till 4-4.5” than move to the 75 continuing the big water changes. When hitting 5” you can go to every other day. This grow out will take at least 6 more months.
