What is the difference, if any, between a denison and red line torpedo barb

Can't see any difference.

 

[markandhisfish]

just 2 different names for the same fish

 

[OldMan47]

They are very hard to tell apart Locker because they are common names for the self same fish.

 

[helterskelter]

The latin name is Puntius denisoni this is where it gets the name "denison", this was named in honer of this person.
Whats why it has an "i" at the end of the name,
