so ive got one light for a 55gal on top of my 125 and the lighting sucks to say the least, i need some advice on what kind of CHEAP lighting i could get to make my tank look good, as of now there no live plants in there but in the future there may be some low to mid level light plants in there. stock is 4 gts i senegal birchir 2 cory cats and 2 spotted pims
