Stocking advice for 75 gallon planted tank

[rabidmurr]

I have a 75 gallon tank that I plan on planting with CO2 and high light, going to carpet with dhg and plant extensively otherwise as well. I have been thinking about getting a school of 9-12 Lake Kutubu Rainbowfish and a small group of around 6 roseline sharks. I was also going to let them be accompanied by some amano shrimp to keep the place clean. Is this tank overstocked, and if so any suggestions to fix it?

What are the tank dimensions (length x width x height)?

What is the GH (general hardness), KH (carbonate hardness) and pH of your water supply?
This information can usually be obtained from your water supply company's website (Water Analysis Report) or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).
