I currently have a 108 t5ho 48 inch. My budget is 490$. I want a 55 gallon tank. I was thinking something like~ 10 rummynose tetra, 20 cardinal tetra, 1 type of pleco???, 6 cory, cherry/ amano shrimp, pair of dwarf cichlids. What would be a good plan for this, I am not set on the type of tetra, maybe rasboras. I also would like c02. The budget could be stretched to $600 dollars. Is 2 wpg good enough to grow plants?
