I'm assuming it is a condy anemone and ime they don't need as much light as other nems like bubble tips and so on. How long have you had the nem? T5 lighting, metal halides or high powered leds will be required to keep stony corals. Softies you can get by with compact fluorescents or power compacts but growth will be slow. T8 will not grow any coral except maybe mushrooms.
20 Gallon SPS reef
29 Gallon FW "fat catfish" tank
20 Gallon Long Dart Frogs "Zig" and "Zag"
what size tank is this for? i would get a 120w dimmable led, then you can grow anything you want and won't have to change the bulbs every 6-12 months like with fluorescent lighting. i got my bridgelux 120w dimmable for 117 dollars
Ok thanks guys how long do LEDs last and what do I search for and where should I look for these dimable lights
they last 50k hours, which if you ran them for 10 hours a day thats 5000 days or over 13 years. t5 bulbs need replacing after a year so it pays for itself. just search 120w dimmable led on ebay and look at the reviews
