hey, Iv'e got 10g and Im not quite sure what light I need. I plan on keeping normal stuff, ricordea, mushrooms, frogspawn...

PS, sorry im such a noob...

hey bro im pretty new to this hobby too but check out my 10 gallon thread i love the nova extreme T5's its more than i will need but with the possibility of expansion

Softies are mostly low light, the frogspawn will need something a little better.

Check out the T5's at fishneedit.com

heres another noobie question:
The tank is 20" but the light in the hood it came with is 18". What size light do I need?

18" or a lot of people use 24".

its not necessarily the length, its the power.....

a fish need it 70 watt halide will cover ya....you wont need another light unless you get a bigger tank

Thank you everybody!
