the smaller ones are not worth it IMHO. Seek a specimen that is 2-3 inches long. You will pay $60 for one that size, but it is worth the money. I don't think any fish has a good survival rate when they are super small. All the literature I have read indicates that really small juveniles or large adults do not ship or acclimate well. Anytime I make an expensive decision about fish, I make sure I wait for the right size fish.

As for the fishfan joke, "clearly" the Tang is bluer than the ocean

Agree w/ the doc.
They are Great fish
I only had one battle w/ ich with mine due to me having it in my 55!

I guess it would depend on the depth and color of the sky at that time to depend on which would be darker. In other words you both would be right. Correct?!?


************************************************** *****
The sea is blue for the same reason that the sky is blue:
In the first place, the sky is blue because the molecules in the atmosphere scatrter the blue part of the spectrum, and the red and yellow parts of the spectrum tend to pass straight through. What happens is that the blue light is absorbed by the molecules in the air; then 're-emitted'. The re-emitted light may get absorbed and emitted many times over before it reaches us. To us looking from the ground, the blue light seems to be coming from everywhere (this is called 'Rayleigh cattereing'); hence the sky seems blue.

The reason why the sea seems blue is similar; but a little more complicated. The sea does reflect the blue colour of the sky (or can appear grey in overcast weather), but this only applies to the surface of the sea. As well as reflecting the blue from the sky, the water molecules scatter the blue light in much the same way as the air molecules in the sky. This accounts for the 'natural faint blue colour'.

In addition, the water also absorbs more of the red and yellow wavelengths than the sky (which warm the sea), leaving the blue part of the spectrum, as well as part of the green. This is why deep water can appear bluish-green. (The absorption of the red wavelengths can be noticed by looking at a red object under deep water. It will appear black; because only blue light is reflected back to us.)

Eventually, at sufficient depth, even the blue light will have been absorbed or scattered away, and deep water will be black and lightless.

these are good things to keep in mind for when we upgrade to our new 90 gallon... I really want a "dory" since we have a nemo...they are such beautiful fish. But, I don't want to take something that is free in the wild and then not have it survive b/c I can't meet its needs. Arguements from both sides...interesting!

And what in the world is that a picture of? my daughter said..."oh, look at it's teeth!"

I just picked up a little 1 1/2" blue tang today, he is tiny, so we will see how he does. I payed around $55, which isn't great, but not bad either, hopefully he will be able to pull through. They have such little fat and they are so active that they need to be fed a lot to have a shot at making it.

get an algae clip and put some nori on it three times a week and you will help it fight disease since blue hippos need all the help they can get

Thanks, thats a good tip.

and what i like to do with my tangs is when i feed them they eat mysis shrimp and they get all there veggie matter from the clip that way they get meat and algea
