Brown and Yellow Tangs: From Friction to Frick and Frack

I have three tangs in a 75-gallon, reef aquarium. I got the blue tang first, the powder-brown tang second, and the yellow tang last. The blue and brown tangs adore each other and team up to eat nuisance algae on the same rocks. So yesterday, I brought the yellow tang home from the LFS. I introduced it to my tank for the first time, and the powder-brown tang went on the war path.

Man, it was brutal, and I vacillated between taking the brown tang out of the tank for a while versus just letting things be, in hopes of having things calm down on their own. Observing the attacks, I thought it most interesting that, every time the brown tang would back into the yellow tang, to try to spike the yellow tang, the yellow tang would gracefully turn to one side, warding off the attack like a kung-fu master. The yellow tang was brave; it did not flee--ever. I liked that graceful display of courage. The yellow tang was also non-violent, and it never attacked the brown tang. I liked that display of peacefulness. The yellow tang simply let the smaller, brown tang continue to wear itself out. By the time I turned the aquarium lights off for the night, the brown tang was still furious, scheming of ways to sneak up on the yellow tang from a new crevice in reef-wall.

I thought I would have to tear down that wall, to get access to the yellow tang with a net, to scoop it out and return it to the LFS. But to my astonishment, this morning, the hate storm blew over. The weirdest sight greeted me: the tangs became companions, gracefully swimming around together, without the slightest trace of hostility. Wow. Saves me a lot of effort in not having to catch and return the yellow tang to the LFS. Now, maybe they'll get back to work, nibbling on nuisance algae for me. Has anyone else experienced this transformation in their tangs, going from friction one day, to Frick and Frack the next?
 
I currently have a ~3" Yellow Eye Kole and a~2.5" Powder Brown in my 46BF QT. The Kole Tang had been in there for 2 months before the PBT was introduced. As expected, the Kole Tang went after the PBT every chance it got for the first 24 hours. The next week, it was spotty, and after that, they get along just fine with no issues. Both will be moved to my 125 shortly.

That being said, do you have an upgrade in the works? I am not sure how well those 3 will do long term in a 75. But glad they worked it out for now!

Thanks, Marshall. You might be right. Time will tell. I am sticking with the 75-gallon tank for the foreseeable future. But it will develop much more with corals, not fish. Hopefully they will blend well, and I definitely won't add a fourth tang. I really want three tangs, if safe to do, for nuisance - algae control. I haven't found a better fish to chow down on the green algae like the tangs do, but I'm open to suggestions if it truly is a bad idea to have the three tangs.
 
A 75 is way to small for three tangs. You can get away with a Yellow alone for awhile, but it will outgrow that tank as well. You really need a larger tank with a longer footprint in the 6' and up range.

Hi, Jaa:

Sounds like you are saying take the yellow tang back and leave it at two, the blue and powder-brown tang?
 
no he is saying there shouldnt be any tangs in there ..

Hi, Nikon:

According to the guidelines you linked, I will have to pull all my tangs and return them to the LFS.
If I wanted a tang, I would have to get another type of tang, altogether, of the following six types:

1. Mimic Surgeonfish;
2. Indian Mimic Sureon Fish;
3. Striated Bristletooth Tang;
4. Kole's Tang;
5. Tomini Tang; and
6. Brown Tang.

Hmm. I'll have to check out which of these I like and can get locally. Thoughts, anyone?
 
Well, based on these guidelines concerning the type of tangs that can go in a 75-gallon tank, I am packing up the yellow tang for a return-trip to the LFS. I suspect that the powder-brown and blue tang will eventually have to go back, as well.

On a separate topic, I suspect that I already have the maximum number of fish that can go in this 75-gallon aquarium. Thus, I probably should not get any more fish, when I return the yellow tang today.

Upon returning the yellow tang, here is what I will have still have in the tank:

  • Clownfish No. 1: ~ 2" long (I've had for 3 years);
  • Clownfish No. 2: ~ 1.5" long (I've had for 3 years);
  • Powder-Brown Tang: ~ 2.5" long (I've had for 1 month); and
  • Blue Tang: ~ 2" long (I've had for 1 month).

Thus, that is 8" of fish for a 75-gallon tank. This is the maxium I should have, per the the 1"-per-10-gallons rule. Is that rule hard and fast? Do the concerns of this rule address one's display-tank size, or does this rule allow "extra credit" for the sump volume, as well, which for me is currently operating at 25-gallons.

What do you all think? Thanks for your advice.
 
There is no hard rule for # of fish per X gallon. As a very very general rule, 1 fish per 10 gallon seems to work well assuming all fish are sized appropriate to the tank. And go by the max size of the fish, not the current size. So for a 75, somewhere between 6-10 fish depending on the sizes of the actual fish. 10 would be for all smaller fish, 6 would be maybe 1 larger, 1-2 medium, and the rest smaller.

Regarding your situation right now, with the 4 fish, 2 being the Tangs, I would probably not add anymore until you rehome both Tangs.

Thanks, Marshall. Very helpful. To remove 1 tang takes as much effort as removing 3 tangs. So I have removed all three tangs. I'll follow the advice recommended and get a Kole tang and follow the numbering suggesting you make. Thanks.
