I would up it to 6 Cory, 5 kuhlis and getting rid of the pleco as they are too big for a 20 and destroy plants.IME. I have a 20 long cycling right now and plan on doing about the same exact stock except I'm doing a pair of gbr instead of a honey gourami. And probably 5 ottos.Was wondering if this would be a good stock for a 20 gallon long planted tank. Tank was set up 3 weeks ago and is cycled (with help from my other tank). I plan on adding 5 panda cory, 8 rummy nose tetra, 1 honey gourami, 1 clown pleco, 4 khuli loach, and a small colony of RCS. I have an aquaclear 50 for heavy duty filtering. Was wondering if this would be a good stock or too much for my 20 gallon long. I'm open to suggestions for new interesting fish. Also, is this too many bottom feeders? I have attached a picture of the layout of my tank.
