If if they eat a lot their growth will still be stunt, especially the ornates as they are in a 90g tank. Too much feeding will produce a lot of waste and waste turns into ammonia which is the one of the causes of growth rate stunt.
They can go without eating for many months, but that's not reccomended. Try starving them for a week or 2. Try feeding them smaller amount that they can consume 3x a day. Also skip meal if they have a full stomach that they look like they atre bloated as they won't try to eat anything and the food will just turn to waste. Once the belly shrink down then feed again.
Here is what I do for example:
Monday - Feeding time 3x
Tuesday - Feeding time 2x
Wednesday - Skip meal
Thursday - Feeding 3x
Friday - Skip meal
Saturday - Feeding time 2x
Sunday - Feeding time 1x
Monday - Skip meal
Tuesday - Feeding time 3x
Wednesday -Feeding time 2x
Thursday - Skip meal
Friday - Feeding time 2x
Saturday - Feeding time 1x
Sunday -Skip meal
