I have a few questions about stocking my tank. I want to put my male dovii in it for sure. He is about 14 inches and he is very aggressive towards people but not highley aggressive towards other fish. I was wondering if the tank is big enough to add in a RTC who is around 12 inches. I also wanted to add some bigger cichlids such as a jag and my RD who is very aggressive towards people and other fish and around 10 inches.
