How Do Fish Recognize Another of their own Species?
It seems they do. Do they say, "hey, there's another Panda Molly! I'll go join them!"
Neon Tetra: "Hey, let's go school with THOSE guys!"
Are fish that smart?
Plus if a female looks quite a bit different than the male, how do they know they're the same and thus, "hey, let's get together!" ?
