Yellow Tang help

[skriz]

I have 5 Yellow Tangs in QT. 3 of them had visible signs of ich, 2 look okay when i bought them. They all went into the same QT anyway.

I plan on keeping them in QT for 4-6 weeks. How often should I be feeding them? I have seen 2 feeding ( I assume the 2 that were without ich), not sure if the others are eating or not. Anything I can do to entice?

Would it be a good idea to re-dip these guys as I clean the QT? (FW, meth blue?)

I have been doing water changes and syphoning the bottom. They have been in QT for 1 week now.

What are you using for biological filtration?

What treatment are you using for the ich?

What are your current water parameters?

What size are the tangs and what size is the QT?

Vitamin B12 has been a good appetite stimulant for many finicky fish. Garlic has helped in some cases as well.

i have s sponge filter that was seeded in my sump.

I ran paraguard for treatment.

Salinity is 1.023, temp 83 deg, ph 8.2

the tngs are 3-4" in a 50g cube QT

update. 2 tangs are very thin. 2 are nice a plump. 1 of the thin ones has a red spot on the forhead and is laying on it's side. Seems like he will be a goner unless I can do something quick.
