Yellow Tang Help

[moohampshire]

I have a 75 gallon bow front tank that has been up and running since this time last year. I keep the ph at 8.2-8.4 and the salinity at .025-.026. Also keep the alkilinity within range. This morning the yellow tanb was mopping along the bottom and I know by the time I get home he will be toast. This is the second one I have lost in the year. Seems they are doing fine and then all of a sudden they are on the bottom and dead. No spots on them like any disease.
Have been doing this for a year. All other fish and corals are doing fine. What am I doing wrong with the tangs.

Thanks for help in advance

They need lots of algae and such in their diet. I always provide them with Nori so they can graze all day long.

Can you expalin to me what Nori is? Excuse my ignorance.

 

[agreeive?fish]

nori = seaweed = algae that tangs need in their diet

you can get it in the ethnic food section of your grocery store

Yellow Tangs are generally very hardy. How are your other fish doing? If they are good then its probably diet. Does your tank have algae if not you need to feed some. Yellows Tangs are mostly herbivores so they need plant matter regularly. Also they love to graze. Nori is the algae sheets used to roll sushi available in any grocery store. Also can try zucchini and lettuce. Vitamin enrich your algae sheets by putting selcon on it and letting it dry.

Nori is a dry sea weed. They sell it at the LFS and in super markets. They have differant colors and most perfer the green one. I would give it once a week. You use a clip that has a suction cup to attach to the glass.

Then i would mix the diet up. I feed flake in the morning and frozen at night , no more then they can eat in 1 min.

Also just in case salt water recieves its oxygen from a gas exchange at the surface. Good steady water flow and an open air space ( no lid ) at the surface will assure high disolved oxygen levels .
