Lettuce for tangs question

I was thinking about getting some lettuce for my tangs. Is it a certain kind of lettuce I need to get? Is better than nori or should I just get some nori?
 
I would go with the nori, just make sure it has no seasonings in it. Lettuce has little to no nutritional value. Romaine lettuce might be a little better, but I would stick to the seaweed.
 
Nori is much better. There is little nutritional value, but if you insist on terrestrial greens, they need to be organic (lack of fertilizers, etc.), should be blanched (fish have a hard time digesting cellulose), and people usually suggest not feeding the outer 2-3 layers.
 
The only terrestrial green is would even bother feeding is some blanched spinach but nori truly is the best if the fish will eat it, and most fish eventually will.
 
I never used terrestial greens. I always used nori to avoid said problems. My clan almost comes outta the tank to get it. They 'll demolish 4 sheets in minutes.
 
another vote for nori - the kind at the supermarket, not the over-priced stale sheets at the LFS.
 
Nori is the best there is for herbivorous fish, IMO.

When I had my first tank, I didn't know about nori and fed my yellow tang lettuce (usually romaine) for about a year. I kept the lettuce in the freezer overnight to help break down the cellulose before feeding it to the fish. The tang did ok but started developing HLLE towards the end of that year. I started feeding it nori instead of lettuce and the HLLE stopped progressing, though it never was reversed.
 
An answer you are shortly going to receive in defense of feeding lettuce, is that pretty much all major public aquariums feed romaine to their tangs.

I am not saying I agree. I figure that it's not possible to feed nori to a large aquarium, and that the tangs IMO get most of their food intake from grazing. The romaine is purely supplemental. For your tangs, stick to Nori.
 
A mixed variety is best.

That being said, I only feed the green kind b/c that's all that is sold at the super markets around here.:lolspin:

Been feeding my crew for the passed 2+ years and they are all fat and happy. If I had access to other kinds of nori I would mix it in.
 
I've fed Julian Sprungs sea veggies sheets in purple and green. When both are on the clip, the purple always gets devoured first.
 
here in SoCal all Asian SM's will have it.

Always roasted and no seasoning.

I imagine all the largest cities will have Asian SM that have it.
 
Greetings All- Does it matter the color of nori? I have seen purple and green nori at my LFS.

Don't get it at the LFS, it's like 10X the price as the Asian market. And at the Asian market you'll get a whole lot more of it for less $$.

Exactly, Asian market is where to get it. That and fish roe, frozen squid, clam etc etc. The Asian market is really a great spot to pick up your tank food...especially if you make your own concoction.

there is no lettuce in the ocean, i would stick with a dies as close to nature as possible

That's always my arguement against lettuce, broccoli, spinach et al. Do they eat it in the wild? No? Ok, then they won't eat it in my tank. ;)
 
I have seen a couple of large public aquarium use bok choy and lettuce. However, the keeper I spoke to said that they feed a large variety of food such as nori, bok choy, local marine algae, etc. The reason for feeding terrestrial greens is that tangs have the need to constantly feed on greens, and these greens are readily available. So with that said, lettuce really does seem to be only supplemental. However, when buying nori from Asian market, choose large sheet of sushi ones not individually packaged nori as individually packaged snack size are for sure seasoned.

Here is a few photos I took while visiting Aquarium of the Pacific. They are having some lettuce. :)

Feeding your fish high quality terrestrial greens aren't going to hurt the fish at all.

The key, as mentioned previously, is to vary the diet.


Some people put up this ridiculous red flag anytime a terrestrial, or otherwise "unnatural" food is proposed. Heads up for all you people, Spirulina (which is found in almost EVERY commercially sold dry food) is a freshwater algae.... and far from something our fish would consume naturally on the reef.
