Hi . The last weekend my 8 years old niece came to my home with this fish .... I know is somekind of tilapia (ugly the poor fish ), but I don't have the guts nor the heart to says to my niece that a I don't want her fish =(.
Do you know what kind of tilapia is?....right now is quarentained in a 20gal. And I don't have Idea where I'm going to house it (I only have S&CA cichlids) .
Thank's a lot

Looks like a sunfish hybrid to me.

Thanks a lot . After searching about sunfishes like you said, I'am almost sure that is a Green Sunfish (or at least half GSF). Thanks again and bye

They sell green Sunfish in Petshops in Germany? Or were they introduced into the river and lakes there?
