In my opinion this is a common mistake. I like to put the fish directly into a large tank and let them be. Water quality is much easier to keep under control and its much less stressful on the fish. One move and their good. Just my opinion and experience.
it's not a common mistake with gars, and actually works better for some species because it will prevent them from breaking their backs and also help with finding food more easily. as you said at the end, it's your opinion and experience, so i'll give you that of course; it works with many other fishes, but with gars it's actually a different story.
i'll try to write more later, but in short, a captive YOY FL gar will not reach 24" overnight...or even in a year...likely not in 2 years. a captive raised from YOY FL reaching 24" is extremely rare, and i'm actually yet to see one (not saying it is impossible, but i'm yet to see one and it WILL take a long time).
you can try to powerfeed and grow them to a large size early on, but you won't hit 24". also keep in mind somatic vs reproductive growth. gars (and most fishes in general) donate more energy to somatic ("regular") growth early in life...they need to get up to size to avoid predators, survive winter, etc etc. once they are at a certain size, which is regulated by several factors, primarily the endocrine system, they switch from donating energy to somatic growth to reproductive growth.
once the gar is donating energy towards reproductive growth (development of the gonads), it will not grow as fast or as large. if you get it up to the size where this switch takes place too quickly, it is likely that your gar won't reach it's max size potential.
does that make sense? please feel free to ask questions so i can clarify further if necessary
