Between mealworm and superworm, which one will last/ survive longer and easier to keep it in order to feed arrowana & stingray over long period of time if I buy large quantity online (roughly about 3000 of them).
Super do last longer but there very fatty and meals are less fatty, but even feeding to much meal worm is something you want to avoid because it can clog their intestinal track.
Super do last longer but there very fatty and meals are less fatty, but even feeding to much meal worm is something you want to avoid because it can clog their intestinal track.
if you want the mealworms to last longer, freeze them. you'll have frozen mealworms for a very long time. this is assuming that your aro will eat not live foods...
You can put mealworms in the fridge, they will essentially hibernate(really they just slow down and will not need to be fed really).
Superworms will die in the fridge, they can't stand the colder temps like mealworms.
Superworms won't change into beetles unless put in isolation(most of the times) so they would be easier to maintain, while mealworms will change into the beetles over times, which isn't neccessarily a bad thing.
