120 gallon Stocking Question

120 gallon Tank

Corals include Duncans, Zoas, Paly's, Acans, Frogspawn, etc.

Current Fish :
Percula Clown
Purple Psuedochromis
Blue Damsel from Hell that is impossible to catch and won't die

Thinking of adding the following
Powder Blue Tang
Gold Rim Surgeonfish, Acanthurus nigricans
Unicorn Tang , Naso unicornis

My son also really like Angels.

First question, would adding the three above be compatible and work out in a 120g??

Second question, what if any Angels would be acceptable??

Thanks
Mark

 

One other follow on question.... Red Mandarin Dragonets??

Tank has been up for a year now...

Could that be added??

Ok, first of all, is it a 4 or 6 foot tank? Either way, a unicorn tang is too large. You will also have to choose between the gold rim and powder blue because they will probably fight being so similar. Pygmy angelfish are all very nice, but there is a chance they will nip/eat corals, and they will definitely eat clams. Dragonets rarely eat frozen food, so you need to make sure you have a TON of pods for him to live off of. They are known for decimating pod populations quickly, so a fuge is a must have unless you have an enormous tank.

 

4' Tank.

Choosing between Gold Rim and Powder Blue leaves the Powder Blue.

Eliminate the Unicorn.

I have a 40 gallon sump/refuge with the tank so the Red Dragonet may well work.

That would leave me with the following:
Percula Clown
Purple Psuedochromis
Blue Damsel

Adding:
Powder Blue Tang
Red Mandarin Dragonet

I am assuming a Powder Brown Tang would fight with the Powder Blue correct??

Are there any other Tangs can I add with that??

 

Yes a powder brown and a powder blue would most likely fight, both being from the genus acanthurus and being similar even within that genus. However, in a 4 foot tank, I would advise going with the powder brown. The powder blue gets bigger and is more aggressive. Just because you have a fuge also doesn't necessarily mean you are all set for a dragonet. Check your tank and make sure there are pods everywhere, because that's what you will need. If possible, wait for the occasional mandarin that will eat frozen, which would take the stress off the pod population.

 

while i agree with the tang and tank length. i disagree about the mandarin.... first there are mandarins that accept frozens its not that rare now, the problem being if it does take frozen, its slow so all your other fish will beat him to the food so you'd have to spot feed him. most angels have a chance of nipping. there are some threads that talk about that so i would suggest looking them up

also one tang is enough in that tank. but between the goldrim and PB you should PM redgambit, hes the "tang geek"
