First of all let me start by saying I'm new to the hobby. I currently have a 75 gallon tank setup with 1 Yellow Lab, 1 Zebra, 2 Kenyii, and 1 Electric Blue Johanni all about 1-2in. I want to add 2 more Kenyii, 2 or 3 labs, 1Y ellow Tail Acei, and possibly 1 Auratus ( which I know can be extremely aggressive). Two part question -1 will the tank be overstocked if new fish added -2 will I run into any compatiblilty issues?
