just picked up a beautiful 7 inch adult female jack dempsey for the 75 gallon tank. My LFS has 5 awesome looking 5-6 inch silver dollar tetras and a very good looking male and female firemouth cichlid. Now i work at the fish store in my town so i slyly have these fish on hold for now since i wanted to consult with you guys! Can i have the female dempsey, a pair of Firemouths and the 5 Silver Dollars in a 75 gallon tank with minimal problems? the dempsey is very laid back, and its a female so id say its pretty much done growing, maybe might add another half inch to an inch but its very laid back. Let me know what you guys think ASAP!
