Trying to I.d this freshwater barrracuda below the redtail. Any help would be greatly appreciate. Believe it to be possibly a yellowtail just not sure.

Looks like a yellow tail but.......has some striping.

It has a hint of a black line on the belly. If it does then insalinae.

Get a side shot once settles in.
 
The smaller one is still has bold black lines but the bigger one looks like the stripes are fading from when I got him and the red is turning orange

They look like insalinae. Wait till they settle down. Basically a smaller cuda than the red and yellow. Keep some floating plants to reduce the stress. Really nice oddball cuda.
 
Maybe it's just me but they somewhat look like isalinae and some ways don't but either way they are eating good and in good health. Thanks

I don't know what to think at this point really lol. Any other species have stripes besides isalinae and nasutus??Only reason I don't believe these to be isalinae is because of the growth they have had within a month from 2inches to 4-5 inches now. Just seems quick for a fish that maxes out at 4-6 inches

Not islanae. The fish with dot behind Gill plate is red tail falcatus. The others are heterolepis possibly. Falcirostris do have black stripe as juveniles, lose it as they grow. Falcirostris have a huge snout though. I see heterolepis bro, could be wrong.
 
heterolepis??? Not even sure what they look like. New one on me. Not to many good photo online when I search that species and very little info
