So i have 4 Sri LAnken wild Etroplus Suratensis in a 125 USg tank with a few paretroplus Dammi. The water is brackish, about 2 tablespoons per gallon, and tasteably salty. The smallest specimen (about 4 inches) has gone very green with a black belly and pelvics and is hanging around with a larger 5 inch species that is an amazing colour, green spots with red/pinkish highlights in teh fins and body. Is it liley that these 2 have already paired up and if so what should i expect? I have bred E. Maculatus and Paretroplus Menarambo so i am guessing it will be similar to these 2. Any thoughts?
