I dont think thats enough light.if your wanting leds i would go with 2x mm box led lights you can find them for around 45.00 each that would give you enough light to keep a bta.
Lovely we told them we wanted to get some corals and and it think we a said an anemone also and that is what they told us to get. They had different tubes maybe there is a strong enough one we put in it
never take advice from petco or petsmart or anyone for that matter always do your own research.
the light you bought is not intended to mantain corals.
anemones require strong lighting t5ho,metal halides are your best bet.
If i was you I would look into getting a 6 bulb t5 fixture you should be able to find one used for under 200.00 including bulbs or as i said above 2x black box 120w led fixture.
I have a 75 gallon tank. Its 4' long & 18" deep. I have 2 t5 fixtures that each have 2 bulbs. They grow bubble tip anemones great! I think you should get a t5 fixture that has 4 bulbs. At least 1 should be actinic. Metal halides work but they are usually used on tanks with more depth. There are a lot of led lights that work great too, but not what you bought.
