Hi guys, I’m quite new to this hobby so I have a few questions for my tank. I have a 15 gallon tank and I plan to put in 18 chili rasboras, 8 pygmy corydoras and 5 amano shrimps. Would that be too much? Is there space for more? I also have the tank by the window(only space in the house my mom allows me to put a fish tank at) would there be any problems? Thanks!
