Am I the only one whom finds LNG to be very easy to convert ?
They have always been the easier for me (Hardest have been spotteds). Then I guess it could also be I have worked with LNG for many years.
Never really had an LNG that was an issue.
Biggest LNG issue is getting them enough food for proper growth. you really do need to pack in the food to these fish to get them to grow right and it needs to be early in it's growth. They seem very quick to stunt if early feeding is not great enough. Odd thing is that even a stunted LNG will live for decades, so I'm not sure all is horrible if they do not reach biologic potential. I'm not suggesting one should strive for a Bonsai LNG but they regularly occur in captivity and often they live quite a long life.
Other gar especially the Atractosteus are more sensitive to reduced growth. Lepisosteus osseus, platyrhinchus seem to be more forgiving. Platostomus and Oculatus are questionable. Platostomus in particular seem to need and require a high amount of food to survive and thrive through their first few years. These fish and LNG are definitely a high energy species.
Oculatus.. well I'm not sure...They keep messing with theories and ideas. They seem much like Platyrhincus but also very different. Known location fish (At least from Michigan) are picky and slightly temperamental. these have been the most difficult fish to work with. They are not quick to changes of diet or environment. They do adapt but it is often a slow process.
