Hello! I'm currently in the process of redoing my 10 gallon and sparkling gourami have caught my eye. Right now my tank has a small school of 6 celestial pearl danios (might add more if possible) and I'm planning on adding 6-8 pygmy corydoras as well. If I were to get sparkling gourami how many should I get with that tank size and stocking? There are a lot of plants in the tank. I've heard that they can be fairly aggressive towards each other so I wanted to hear from people with experience. Thank you to anyone that can give advice!
