Too much nori?

My kole yellow eye tang is going through Nori like a kid that just went trick or treating for the first time. Can he have too much? Currently I'm giving him all he can eat, just concerned that too much of a good thing can just be too much.

Thanks

Kole Feeding,
Though this species feeds almost exclusively on attached filamentous Green & Red algae species in the wild, it generally adapts quickly to other food formats and kinds in captivity. Some meaty foods like Cyclop-Eeze, Mysids and Artemia are a good idea to mix in at least weekly, with live algae (Gracilaria/Ogo, Spirulina...) being best, prepared algae products like Nori wafer not often taken. Of course, having an abundance of healthy live rock with its constituent algal component will go a long way to providing continuous forage for your Bristlemouth Tang.
 
Thanks for the link. Really doesn't answer my question though. I have a decent amount of large rock for grazing, and he on occasion will pick at the foods I add for my other fish, including mysid, and cyclop eeze.
After reading all the posts about Tangs NOT eating, I'm thrilled with his eating habits... I just know that some animals have the instinct to stop eating before they get sick and some don't. If I left food out consistently for my yellow lab mix, he would eventually eat so much that he wouldn't be able to walk. Just trying to make sure by always having the nori available, I'm not doing the same for the tang.
 
I would think a sheet for breakfast and a sheet for supper would be good :) just my opinion since we don't know how big it is. What is a decent amount of rock?
 
75 gallon tank (non standard 5ft by 18 by 18) He's about 3 inches. About 90 pounds LR in basically two islands so as to allow for swimming room. (50 marco, the rest was LR from the LFS and from another tank... ) tank is 6 months old. He has three chromis and a lawnmower blenny as tank mates now. (I know the blenny is enjoying the nori also) Going through about three sheets a day now, but the blenny is helping. Haven't kept a tang before, and all the threads I've read seem to point to them NOT eating and no one seems to address how much is too much, or if that is even possible... but I could just be a terrible searcher!
 
About all fish can overeat in captivity. I would still say 2 sheets would be fine. Having any algae issues? Running gfo? How big is the lawnmower?

I help feed a 11" Vlamingi tang, yellow tang, purple tang, blue tang and a
maculiceps tang all in the same tank and feed 1 sheet or 2 of nori in am and one in the afternoon along with formula 1 pellets.

Unless the fish is noticeably overweight, I'm sure you're fine. I'd think your water quality would be in more danger than the fish.
 
No algae problems, no health problems, please don't make me say that ever again *knocking on wood*
the blenny is about 2 1/2 inches... nice and fat.
Not running GFO, all RO/DI from the start, ran some phosban and carbon in a hang on for a while when I had the normal new tank cyano and HA in the initial cycle.
I'll hold at where I'm at for now, and watch to make sure he stays fat and healthy... increase as needed. Don't know if he'd stop or not if I added more, because I haven't. Was just a bit afraid of overdoing it.
 
ok sounds like it's fine :) Watch for phosphates. Those tangs can sure POO!!!! I'd add gfo just because. I won't run another tank without it. Also, keep carbon on hand. If anything is ever amiss in your tank and you suspect containment then you can throw carbon in a reactor quicker than you can change water, unless you always keep water at the ready. Nothing like having a disaster at the worst moment so I try to mention this. Sorry if you already know :bounce3:
 
I have a bristletooth tang in my 125g. Won't touch nori, and won't touch live sea lettuce. I've offerred it both on numerous occasions.. If it did touch the nori (I can't prove it didnt' since it would usually end up in the tank after a few hours, then disappear to the snails / crabs, or who knows what else... I would only put half a sheet in once every couple days and that would just stay there until it started disolving until it just fell off the clip..

However, if I feed vitamin soaked brine and mysys shrimp, that bristletooth goes nuts. It'll eat whole mysis shripm faster than my marine betta can open his large mouth to think about eating a piece of shrimp.

I can't believe how much meat my bristletooth eats... I'm just happy he eats! He does peck at the glass and occasionally I see him pulling strands of HA off the rocks....

So, he must get enough fiber from the algae in the tank.. Some days I'll come home and see kiss marks all over the glass.
 
I have some recent pictures I took of tangs in Hawaii. They are unbelievably fat, so thick it just looks silly. I've never yet seen a picture of a fish in a tank that looks as healthily plump as most all fish in the ocean do.

I wouldn't worry at all about over feeding your tang. Feed it as much as you can without compromising water quality. After all, they graze ALL DAY LONG in the wild, they dont just get one or two meals and then nothing. So I'd just feed to your hearts content, I've started adopting that method with my current tank, I feed many small meals throughout the day and I think, although it's just a feeling and not quantifiable evidence, that my fish are healthier and less aggressive because of it.

Long story short, I dont feel there is such a thing as too much nori. I feed lots of it, along with NLS pellets and my fish are still no where near their wild counterparts as far as weight or thickness is concerned.
 
I feed a lot of nori and flake. Here is a slightly blurry picture of my footballish Dejardini

The more you feed the more they poop. Keep and eye on your water chemistry and your fine. Tangs are pigs and will foul up a tank pretty fast. With that said, a fat fish is a happy fish.
