Fish ID, some sort of tilapia or ????

[santoury]

A "not big" tilapia is as you said, about 8 to 10 inches. There are a couple rarer Oreochromis that are more like 5-8 inches, but those are rare and can usually only be bought from specialty breeders online, and even then, they are rarely available.

But luckily for you, yours is on the smaller side of the scale - 8 inches or so.
The rest grow over a foot long. But alas, the mariae is one of the more aggressive ones.

The mariae is known for its aggressiveness. The mossambicus are generally only aggressive when males are breeding, then they turn nasty. Most Oreochromines are pretty mellow except for a few species that are given to chasing and biting such as niloticus. The Tilapia ssp are more aggressive - especially mariae and buttikoferi.
