Think that is too easy if the fish were in the tank, don't you think so?
Well, no not really. Considering that there are multiple Paratheraps that, when stressed and pale, will look incredibly similar to one another. That's pretty much going to make it a guessing game instead of actually being able to apply knowledge of the traits of the fish to make the ID.
So, ok how about P. guttulatus?
