So I have just a 20g long with a single ocellaris and CUC. I want to get a BTA for my clown, but I do not have strong enough lighting (1 T8 fluorescent bulb, 20W). I have seen several people have success with LEDs, which I would prefer because they look much cheaper than T5's, but I do not know if the wattage/gallon is different for those.

What type of LEDs would be best, how much do I need, or should I bite the bullet and go with the T5s?

Thanks!

In the first place I wouldn't put a RBTA in a 20g tank, ESPECIALLY if it's less than 12 months old. A clownfish does not need an anemone. I have a pair in a 125g tank with 10 RBTA's and they don't even go near them!

Your tank is shallow so any led aquarium fixture, even the Current Orbit (fish only or very shallow tanks) will work. The Mars Aqua, at less than $100, is probably the least expensive. And on a shallow tank, you will probably run it at about 1/4 to 1/3 of full power, something like 30% to 40% blue and 10% to 20% white.

LEDs are "so much cheaper" than T5s?

Make sure you are looking at aquarium/reef specific LED fixtures.

$160 for an led fixture with lots of control seems reasonable to me. Yes it's a Current Orbit fixture, but the OP's tank is a 20g long and this will grow anything in a tank this shallow.

One semi affordable option would be an AI Prime HD. $225. I'm using one to light an 18x24x18 tank with three BTAs in it. It's a single puck so it won't light every corner of the tank, but it'll do fine for a BTA. And you can always just add more of them if you want to get a bigger tank. I may add a second one but things have been growing fine with just the single light.

I see no issue keeping a BTA in a 20 gallon. They are not particularly demanding.
