Those are my first Cichla(I had before but for 3 mounts only ).I believe the bigger one is orino and the smaller mono.I have them for few days now and the mono try’s to eat flowting pellets, but spits them out and the orino gets them.They have no interest in any frozen food.The smaller one also have a sunken belly, but he is attacking the food and even my hand(seems to be the more aggressive one).So should I treat them or just wait and change the The food .Thanks in advise guys.
