Questio about lighting

[luckyk0505]

What kind of lighting are u using on your Fish only tank?
I am using one 40 watts Coral Life My friend told me it is
too small for Fish only tank he said metal is good lighting but
for fish only and soft coral tank 4 x 40 watts is ok

A fish only aquarium does not need metal halides, you should be fine with the 40 wats that you have right now. All you need light for is so that you can see your happy little fish. Down the road though if you wanted to add corals you would need to get a better lighting system.
