Thanks! The tank is pretty small: 15 gal. I had the stand, hood, and filter from my old 10g so this size was perfect for me (same foot print as the 10g).
Koko, those fish are platies (born in my tank

)
Jsrtist, you are not alone... I might be the only one in this board who cannot grow Java moss. I have tried a couple of times without good results <_< .
