Hole in the head

Ammonia?? How long has it been since your tank cycled? How many and what fish do you have in your tank?

Although tangs like non veggie food from time to time all tangs except the blue tang need algae to live and grow. What is the first ingredient on the NLS pellet label. It should be spirulina.
Go to the LFS and buy Wardleys spirulina discs or pellets. Wardley because it is spirulina.
Go to an Asian market and buy non flavoured nori.

You should be dropping in a couple of discs at least twice a day and have some nori on a clip.
Tangs feed all the time throughout the day.

It is important to use garlic extract when you add a tang to ward off ich but I would not be using it and the other stuff daily. Use selcon soaked food now and than.

thanks for the great info

all carbon was removed the reason for cabon in the first place to remove a little metroplex as i had a stressed out firefish who devopled a little ick. i just never removed it thinking no harm.

and as for the ammonia it was from adding a little to much lr at one time and my ph probe was out of cal. but it was shortlived and is better now

i just did a test on the water prior to water change and nitraes were at 5 and ammonia was at 0.1.

thanks for the advice on feed and food soak. i do use frozen spirulina product daily but i will look intothe wardleys
would it be wise to start a antibiotic or just to travel the road

[Proteus]

sorry tank is a year old give or take a month

[naesco]

No you do not need antibiotics. You need to get the ammonia to zero.

[Jason McK]

Ammonia to zero and increase the nori or speralina based foods.

Ammonia will be 0 ASAP my fuge was jousting my brothers fish as he was moving plus adding new rock. A little much on billows but fugue is m t now and water changes were done I will increase plant matter foods

Is there any veggies I can feed him. That may do good

[Proteus]

K well after taking all advice by increasing plant based foods and ensuring water quality the mark has become smaller buy Alot and seems to be scabbed over it is now about a pin head in size

Thanks to all the people who helped. I will keep a eye on him.

Correct, but that does not equate to any tang requiring spirulina as the main part of its daily nutrient intake.

The optimum nutrient intake for tangs is far more complex than simply feeding them aquatic based plant matter in large amounts. Furthermore the premium pelleted diet known not to induce HLLE that was mentioned in the article on HLLE that was linked to above, was NLS, as was the pellet food used in the study by Tilghman, et-al that took place almost a decade ago.
