Specimens are a little more mature…So bigger and potentially more sharp/hard parts on them. Definitely not good (whole) for teeny tiny turtles but my 5 inch juvenile Painted handled most of them okay (the size varies- I even found one ‘big’ [2”?] shrimp in the jar?.I imagine these would be fantastic for outdoor fish, as intended.They didn’t seem ‘as’ stinky as the others I’ve bought…which actually lead me to think that the major US brands {NOT THIS PRODUCT} are probably adding all kinds of crap to them…Not to mention all my turtles we’re not getting proper nutrition when the US brands of freeze-dried (mini)shrimp were a staple of their diet…they became Vitamin A deficient and suddenly had serious eye issues. Hard lesson learned.The other brands I’ve gotten (Petsmart, Pet Supplies Plus) look like they’re freeze dried…But these actually just look like shrimp- that are dried ? hard to explain… they just look different; they look REAL, and have substance to their bodies unlike the others that just look like outer shell [skin].These are a paler pink and NOT translucent.US brands I’ve bought (3 different), or seen; are redder, and have a translucent quality to them…like a ‘shell’ with little substance.?After visiting all the stores to search for a deal on dried shrimp, and then looking online, and scouring Amazon… I landed on this container because it was the largest amount for the best price. I couldn’t even really find bigger amounts like this container offers. I quickly realized it made sense to search for ‘Koi’ food -knowing Koi being primarily an Asian thing- so I even searched that somewhat extensively as well; even using the actual origin names of the Asian fish? hoping to find a cheaper overseas option since these things are SOOO marked up here.Point? ? Just get these lol save yourself lots of time. Unless you need teeny tiny ones for some reason- then seek another product, or see if running them in a foot processor could do the trick ??‍♀️
