Planning on stocking a heavily planted, aquascape-heavy tank for my first tank. Tank is a 15 gallon (tall i think). I want to put: - 5 Red Cherry Shrimp (hopefully will develop into a colony) - 6 Otocinclus Catfish - _?_ Red-Belly X-Ray Tetras or Ember Tetras I'd rather have the tank be understocked and have the main focus of the tank be the aquascape. *I'm wondering if: 1) Having 6 Otocinclus is too much for the tank. 2) Should I add any tetras, or would it overstock? Thanks for the help!
