Ok, so I was going to be getting a 55 gallon tank but then my mom saw how big it was and flipped out. So now I am getting a 40 gallon (maybe a 46 gallon bowfront). Need help with stocking. I already have 2 serpae tetras, a longfin black skirt tetra and a pleco. I am not sure what can go with these. Would love to have an angelfish and rainbow shark. Please help.
