Yellow Tang and stocking level questions

[Floyd]

This might be a stupid question but what is the smallest size a yellow tang should be in. My 46 bow currently has,

1.tiny wild ocelaris
1.small to medium tank raised percula
1.tiny yellow clown goby
55 lbs live rock(fiji)
8-12 snails
8-12 assorted small hermits

coral includes

frogspawn frag(3heads)
hammer frag (3heads)
3 mushrooms
2 patches of xenia
1 patch of anthalia
4 patches of star poyps(3greem 1 brown)
2 frags of what might be leathers
1 mushroom looking thing that isnt a mushroom

Now what I need to know is what can I add. I am planning on adding another yellow clown goby and a green clown goby. I dont want it to be overcrowded but now there not that much movement I would like a little more.

Floyd,

To be perfectly honest, I think the smallest tank for a yellow tang should be at least 75g tank. Not that you can;t keep it in a 46g tank while it is a tiny juvenile, but do understand that it will have to be moved in about a year to a larger tank. I am not from a tang police either... ;)

I figured, so that is out what else would be good to add

Floyd,

There is a miriad of very interesting gobies and blennies that you could chose from. I think they make a wonderful additions in a smaller tanks and the fact that they remain small helps a ton.
Check www.fishbase.org for your research, if anything, I think a Pistol shrimp ( Alpheus randalli) and a Stonogobiops nematods would make an exellent addition, providing that you can find a pair.
