I have a 55 gallon tank and it has never been used before. I have a eheim pro 2 canister for up to 90 gallons right now. I am not sure on what fish to get. I just want a nice looking tank and fish. I don't care if it's one fish or 20 fish. I just want some ideas and I will go from there. Also I am planning on using bio spira to cycle the tank. Anyone tried it before?
