Ummm you know what i havent looked into the family of leaf fish, but i cant imagine that theres more than like 5 species of leaf fish, or at least that how much i know of leaf fish lol. They get 8 inches and have a very large mouth, and if they wanted to could easily consume a fish their size, it woudnt fit in their tummy though haha.
No its not a bass its a species of leaf fish called nandus nandus or asian leaf fish or gangetic leaf fish, all the same. They do closely resemble bass though i must say.
