Very simple lighting question...

Okay, this may be a stupid question (remember I'm a beginner)

I got live rock and live sand in a tank right now. I put some blue LED lights instead of the fish light that came with the tank. I heard that only coral and aneneme need light and fish are not too concerned with lighting. I don't plan on doing coral and aneneme, is this setup okay? Picture below.

 

yes it's ok but I would buy atleast a cheap light of some kind so you can see the fish and they don't live in twilight.

one thing you may notice if the lights isn't bright enough the fish will stay whitish. the pigment in their skin responds to light.

 

im no light expert, but with the wrong spectrum of lighting it can possibly cause algae blooms too. For that reason it is important for most to replace their bulbs at a frequency otherwise algae will grow like crazy. Probably not an issue in your case but something to look into.
I'm not sure though with your LED's, i may be way off "par"
I bet your tank looks really cool at night BTW.

 

I would remove the bubbler. Will cause a lot of problems for you from saltcreep to ruining what the water lands on after the bubbles pop.

Lighting is all about preference. If you like the blue LEDs keep them.

 

ok guys thanks a lot for your replies!

 

It's a bit dark; I would get some more LEDs or something so you can actually see into the tank and the fish realize it's daytime when they're on. I would just make sure that you don't get bulbs that are high in PAR.

 

Get a strip of white LEDs to turn on a few hours a day. Tank and rock look great.
