nice tank i started with a 125 also i give it about 6 months and you will wish you held out for bigger, i did lol. as for lighting it should be enough for now (unless you going to go for planted). i would save my money for filtration try and get an fx5 on that sucker i had two on mine right before upgrading to 240 and the water was crystal then and now. what are your plans for decoration? sand/gravel/bare?
