Help! I will be setting up a 75 gallon tank in the next 2 months and I have been trying to figure out a setup for the last 2 months. I've really been thinking of a 'river' tank with good flow and minimal plants but most of the fish I am interested in need a planted tank. I was going to make it sub-tropical but I feel more limited in my choices of fish. Some of the fish I have considered are Giant Danios, Bloodfin Tetras, Harlequin Rasboras, Cherry Barbs, Fork-tailed Rainbow. I also really wanted a Tiger Pleco but it is more suited to a tropical setup. I really like the look of a large school of fish swimming in the current. I already have Rummy Nose Tetras in my 45 tank so I don't want to duplicate. I babble on. I would really like some ideas on a fun setup for my 75 gallon. Any ideas would be greatly appreciated. PS I will have a canister filter and a power head to create flow.
