I have a dark blue florescent light on one of my aquariums, I'm wondering if this light is healthy for my fish. In the tank I have 5 zebra danios and 3 glo danios and 6 neon tetras. I have a regular florescent light that came with the tank. right now I have fake plants, but would like to switch to real plants.

Welcome to Fishlore!
Are you talking about a an actinic bulb? What size tank are these fish in? I would up the danios to 6 because they are schooling fish.

I have a 25 gallon long tank. Yes it's actinic blue spectral peak T8 bulb.

Yeah the fish should be fine. Those actinic bulbs are mostly used for Saltwater tanks. They look nice though

If I read it correctly the 5 zebras and 3 glofish danios, they already have a school of 8. They are both the same species. Alison

What's best for them? The blue or the white light?

You are right. I thought they wouldn't school together because they are regular zebra danios and glo fish danios. I just read that they can school because they are identical

There really isn't a "best " light for them. But if you want a cool effect on the glo fish, you can buy a moonlight

What about for growing live plants?

I don't think the actinic bulb will grow live plants. If you want to grow live plants, get a bulb in the 5000k-7000k range. Preferably 6500k because this is bulb is more ideal for plants.

Absolutely do not run actinics on a freshwater tank. You will have so many algae problems. Just wanted to make sure you know that.

6500k bulbs for growing plants. If you run with LEDs give Finnex a shot.

OK thanks. I changed the light in my tank to the bright light that came with it.
