Hello, i just registered, So im new here my question is if i can add any more fish to my 10 gal tank. I would like to add a suckerfish like a pitbull pleco or an oto. But i've heard they are schooling fish. Currently I have: 3 guppies 1 molly (but she will be moving out cause i heard they grow big) 1 Amano shrimp The tank is also heavily planted with 5 plants. And i do weekly 20% Water changes. My Water parameters are all stable. So could i add any more fish like a pair of otos or a group of galaxy rasboras ( celestial pearl danios) or should i leave my tank as it is?
