What kind of lighting?

[yannifish]

They fit into flourescent fixtures don't they? Should I have one big one of two little ones?

I have a 150 metal halide pendant over my 25 gallon and I love it. I did a lot of research before picking a light. I read and read until I though my eyes would fall out. Make sure you think long term. You dont want to buy a light and realize it doesnt suit your needs and have to buy another one. Sometimes you just have to be patient and bite the bullet. Do lots of research on lighting and what your intentions are of what you want to keep. Impulse buying is bad.
