What would be the Minimum lights for a Haddoni

Thanks for the links, but I don't fully agree with the second one -- and I am aware of who wrote it. I don't like using watts per gallon, which was used in that link. And don't feel that we as hobbyist should strive to have our anemones survive, but instead so aim to have them thrive.

I am going off of my personally experiences with both S. haddoni and E. quadricolor (( had an S. haddoni for 12+ years )), and you are free to disagree with all the literature that you want.
 
Wait, am I disagreeing with the literature or are you? I am just curious.. I have not kept haddoni for 15 yrs nor kept it under anything less then a 250 halide.. But I had that on a 120 and I wouldn't really call it a high light environment..

Most of what I read says haddoni are pretty easy to keep once you get past the shipping and are able to adapt to lower lighting conditions.. As opposed to some other anemones.

The second link is written a while back I assume.. Back then when we all had PC lights watts per gallon was a little more widely used.. But I agree it doesn't really tell us much, especially without tank size and depth.

I just feel there is a sort of misconception that haddoni are super light hungry SPS, gigantea type animals and are impossible to keep... And as far as I can tell they are not quite that needy.. Would you agree?
 
No, I don't agree -- for the most part. IME, S. haddoni can SURVIVE under less lights then a Gig/Mag ((whereas the Gig/Mag might actually perish )), but do so much better under "high" lights -- for me that would be 2*250 MH + 4*54 T5 over a 75. Sure, my tan S. haddoni survived under 6*65 PC over that same 75, but when I switched lights it was light getting a completely different anemone.
 
i think todd's just trying to say yes, they will live in a poor lighter quality, but will they thrive, grow, and be amazing? .. (im no expert and i find myself messaging todd all the time haha)

That is pretty much what I am trying to get at -- thanks.


Yes, they were live/survive, but they will not thrive -- that is what we should strive for.

Todd, what are you getting at here? Are you trying to say the nem got larger, stickier or more vibrant? Perhaps a combination? If you could, please specify.

Yep -- to all 3.

Its growth took off -- with very little direct feedings, perhaps 4 pieces of krill once a month, at best.
While it was always sticky, it become stickier and quicker to respond, to both food and my hand.
Vibrant would be a good word to describe the color change. While still tan is color is wasn't nearly as dull, in color -- if that makes since.
 
IME, haddoni requires much more light than magnifica. I would rank gigantea as the most light demanding, fallowed by haddoni, then magnifica. Their natural habitat seems to correspond with what I've seen with these three species. Gigantea is found in very shallow water, haddoni can be found deeper than gigantea, and magnifica can be found deeper than either of them.

I'm with Todd on this lighting thing. Haddoni, if healthy to begin with, may be able to survive with lighting that isn't favorable, but that's about all it will do, survive. It's a completely different animal under good quality, bright lighting. Their color is better, there are fewer gaps between the tentacles, feeding response is better, growth is better, everything about the animal seems better under better lighting. After seeing the difference first hand, I'll never keep my haddoni under lower lighting conditions.
 
My experience has always been that Haddoni doesn't seem to care as much about light as Gig's or Mag's, often not residing in the brightest areas of the sand bed.. Where as Gig's and Mags always seem to look for full light on their oral disc...

I also spend a lot of time reading and most of it says that Mags and gigs are the most light hungry, mag occur at depths mostly from 5-20m.. Haddoni has a very similar depth range..

It is also much easier to meet the husbandry needs of haddoni than the other carpet like anemones.. They may just be more tolerant of water quality and flow.. And so may be more able to adapt to lower lighting with supplemental feedings.. And thus my perception that they are not as light hungry.... I do not know and have no clear evidence either way.
 
Ive tried haddoni's under T5s and either I could never get healthy ones to begin with or the lighting wasn't enough.

I quit trying haddoni's until I got a new tank with 2 400w MH. Funny enough the first 3 haddoni's I put in this new tank are thriving. Colors are improving, tentacles are incredibly sticky and they settled in very quickly.

(one exception, my red one got blown into the back of the tank, first day in tank, and it has been slowly moving its way into the light)
 
What I don't get is.. how come some diver's say they find haddoni's 70' deep.. They aren't getting much light that deep! I too agree they like high lights, as when I boosted my LEDs up, my red haddoni expands and got much bigger. I didn't think T5s are that weak though. If you have a par meter, you should check how much par you're getting at your sand bed under the 4x54 T5

One comment about a small handful of S. haddonis being found at 70' is not the norm for them. I can't find it at the moment, but there is a web site out there that has tons of photos of them darn near out of the water at low tide.

I can tell you that, back when I had my red S. haddoni is did wonderful under 2*250+4*54 T5. I will never keep an S. haddoni under less lights.

Im going to bump this thread up and ask a Haddoni-related lighting question....
How do you feel about the need for point-source lighting vs T5 or PCs?
 
That is definitely an improvement.
My question is really as follows: let's say you have a quality t5 fixture like an ATI powermodule on one tank, and 2x metal halides on the other tank. All else being exactly the same, including flow, feeding, water parameters, PAR values, etc... Will the haddoni be happier under the point source lighting like mh or LEDs, or will it do just as well under the T5 fixture?
 
I don't think point source is all that important with haddoni. With other anemones that are more prone to moving, like magnifica, I believe this becomes more important.
 
With my magnificas, they are directly under an ATI Sunpower and I've seen no movement. I've kept them under MH in the past and actually feel (quality) T-5s is a preferable light source for this species. I know that some have posted about mags needing point-source light, but that hasn't been my experience.
 
That's good to read. I'm trying to decide if upgrading my Aquactinics Tx5 to an ATI Powermodule or 2x MH/ 2x led fixtures would be worth it.
I'm leaning toward a 4 bulb Powermodule right now.
