Hello everyone I currently have 5- Cory Cats, 1-Bristlenose Pleco, 7 Black Skirt Tetras in a Tank. I am wondering about getting a single Dwarf or Pearl Gourami to finish off the tank with some color. Will the Tetras work well with a single gourami and which would be the best gourami to work with them? Any advise would be appreciated. Thanks!
