Im working on a new tank that will be inside another tank so it looks like the fish are swimming together. So roughly the inside tank will be 100 and the outside will be roughly 150. Soing this so i can put probably peaceful fish in one tank and aggresive fish in the other one. And make it look like they are swimming together. So any ideas on stocking? Not sure what fish will be in what tank so you can give ideas for both tanks. And see what works.
