How long to leave nori in the tank?
 

Had an LFS guy who is pretty knowledgeable tell me that you should take nori out of the tank after 4-5 hours, but I don't understand why. How long do you leave nori in your tanks?

Not sure how long, but it'll start to rot if you leave it in too long. That turns into ammonia, then nitrite, nitrate. You know the drill :)

My fish make sure my nori stays no longer than 10 minutes.....

Why are you putting in more than they can eat? I only put in enough to last maybe 2 hours. My yellow tang and blue tang finish it off and there is no need to remove any leftovers.

I believe the package says no more than 24 hours

I have a Hippo in QT and he's been eating caulerpa, which I don't want to put in my display tank. So I am going to be adding the nori. I'm just trying to find out what the issues are with leaving it in there.

I hand feed strips of it to my fish throughout the day. It doesn't sit in my tank at all.

Is it unusal for a Kole Tang to eat mysid shrimp?
I figured that because it was a tang it would eat caulerpa and/or nori and foods of that sort. But my Kole only seems interested in shrimp and general tank grazing.

I throw in a strip 2 or 3 times a day for my Naso Tang. He makes quick work of it. It's gone in about 2 minutes. He loves for me to let it float so he can come up from underneath and "attack" it.

I'm not a big fan of letting food sit in the tank for too long. Once in a while I will take a strip of Nori and tie it to a rock so my inverts can munch on it. Once an hour or two have gone by I usually remove whatever is left.

I've got an achilles in QT. He doesn't always eat nori while I'm there, but if I come back a few hours later, he's devoured anything I left in the tank.

I fold about a 3x4 inch piece and mount into a lettuce clip and soak with a bit of Zoe and/or Zoecon. It's gone in a matter of minutes between my Blue and Yellow Tangs. My lawnmower has started going after it as well. He sees how excited the Tangs are and says to himself I must be missing something here. I better taste this stuff. Pretty comical.

Ya, if your fish aren't finishing off the nori with a quickness, you're putting in way too much.

Then again, I've got four (fat) tangs... :lol:

(Pacific Blue, Yellow, Sailfin, Powder blue)

<----- Not a tang expert :P

What is nori? Is that the dried sea weed? I have just started putting in a bit of that on a clip for my yellow tang in QT. Some days he seems to eat the whole thing up, others he doest touch it. I do try and remove any left overs the next day if he hasnt eaten it though. You guys saying I should only leave it in there for a matter of hours????

ive only recently tried nori on my foxface and 2 dwarf angels and nobody seems interested in it....the angels just pick at the micro algae and the foxface just eats caulerpa. So i only leave the nori in there for 24 hours. Hopefully they will discover it soon....

Yes, dried sea weed. "nori" is just the japanese word for it.

Its also used in sushi rolls. :D

It is the dried seaweed. I buy mine at the local Asian food market. Costs me about $1.59 to $1.79 for a ten sheet pack. The sheets are about 5-6 inches square. My french angel and regal blue tang wipe it out in minutes usually. On rare occassions, I will see some left the next morning, about 9 hours later, but it always gets finished soon after.

My yellow tank likes to rip the whole thing of the clip and let it float around. BRAT!!! :D

My huge Mexican Astro snail jumps right on it....eats any left.
