I'm starting a new tank (community tank) and I'm having problems with kind different types or species of fish in my 55 gallon tank (4ft and a couple inches long). I have plan out my idea: densely planted, flourite substrate, and I'm still planning, here are the fishes I'm also think of putting in my 55 gallon: 5 Gouramis, 6 White Cloud Mountain Minnows, 6 Zebra Danios, 5 Black Skirt tetra, 3 sword tails and platties, 4 Cherry Barbs, 6 black phantom tetra, and 3 common pleco. I'm looking for good suggestions on any changes to my (planned) tank, thank you. My tank is already cycled, just to let you guys know. Sorry to the 3 or 4 replier, but I use the aquarium calculator and found out i have a 75 or 79 gallon tank, I'm very sorry.
