Tang Aggression - Understanding and Combating

[Wen]

I purchased a juvenile Caribbean blue off DD out of sympathy and need your advice on whether to keep it or move it along.

I have 2 tanks going now (150 dt and 30 observation) and a 280 coming in March. 150 is leaving.

What’s your opinion on housing together:
Whitetail bristletooth 4”
Caribbean blue 3”
Convict tang trio? or 1? (On purchase list)
Bellus 4”
Copper band 4”

(Clowns, bundoon blennys, flame hawk, chalk basslet)

New set up is 280 gal peninsula 64” x 30” x 34” height, 3 rock islands for fish to easily circle.

Thank you.

It can be done, my only concern is Caribbean blue are fast growers, get quite large very quickly, and can be pretty aggressive. I still think you’ll be OK but it may not tolerate convict tangs, so if you have an issue that would be it.

I currently have 2 yellow tangs, blue hippo, and naso along with a MI and FF. I wanted to add a purple tang or white cheek. Is it doable?

What size is your tank?

 

[Katrina71]

You guys have experience with tangs. We are upgrading to a 93 cube. Is there a Tang that would be compatible with a tailspot and small gobies? Always had a peaceful tank. We'd like to keep it that way.

 

[4FordFamily]

I personally wouldn’t keep a tang in a 93 cube but a juvenile flame fin might be OK for a very short time if you planned to upgrade later. Tail spot don’t generally tangle with tangs

Scopas tang is also pretty small and chill

 

[litenyaup]

Great info thanks for sharing your experience!

Scopas Tang is one of the larger Zebrasoma. Larger than Yellow or Purple.

 

[pdxmonkeyboy]

While this is true, they are also some of the slowest growing tangs.

I have a long established yellow and am considering adding a convict tang. This is in a 120 gallon tank. I would use an acclimation box. What are the chances of this working? Get a small convict?

Just need some thoughts and advice. I have a 240gal DT.
Stock already in tank: @ clowns, 1 royal gramma, 1 bi-color blenny, 1 redline wrasse, 1 rubyheaded wrasse, 3 green chromis, 1 7" foxface, 1 2 1/2" Naso tang, 1 2" yellow tang and 1- 1 1/2 sailfin tang.
I have 1- 3" yellow eyed kole tang and 1- 4-5" banner butterfly in a qt and 1- 1 1/2" hippo in another. next week they are done with qt and plan to add all the 3 at one time. At first had the 3 qt fish together but there was a lot of aggression between the kole and butterfly fish. the hippo stayed hidden. I had to put a divider in the tank and moved the hippo to it's own tank to make sure it ate well and got use to me. after a week the kole and butterfly worked out their differences. The little hippo has been eating like a pig and comes right up to the glass when I feed.
Does my plan soud ok to add them all at once to the large tank. No big issues with aggression in there. the foxface is the boss at the moment and only bumps the tangs when they get in his path. No one is activily bulleying anyone except between the clowns. it has been almost 2 months since I added the 3 tangs to the DT.
My main concern it my hippo since it is so small. but not planning on adding anymore so feel I need to add with this batch as a group.

Great thread! I used your tactic of the zebrasoma trio and it worked great. Bit of chasing the first few days but they're all good now. Loving the tank. Currently have 6 tangs(in order of newest to oldest): purple, yellow, desjardinii, yellow eye kole, tomini, and naso. Other fish to consider that occasionally get wrapped up in tang business--foxface, lamarck angel. Naso is biggest, and gentlest, tomini is smallest but seems to be the one stirring things up if something is going on.

I was hoping to add a few more fish and was wondering your thoughts. Do you think the trio approach would work with athancurus as well? I would really like to add an A. Japonicus, a clown tang(still not sure if a good idea...thoughts?), and possibly a PBT. I'm also hoping to throw in a blue jaw trigger to round out the gang. What are your thoughts on that? All would be QT'd and treated, but do you think that stock would be doable? I'm thinking I'd have to do another all-at-once introduction. With that many tangs, do you think the clown will be alright being introduced so late? I could also see just doing two Acanthurus and the bluejaw, perhaps?

Thanks a ton!

Adding a single tang to an existing tang is perhaps worst-case scenario. The yellow is likely to be VERY territorial. It could work, but it might not. In a 120 I don't know that adding other tangs with it is advised. They're different enough it MAY work but I could see the yellow really not accepting his new tankmate. Zebrasoma tangs (such as yellow) often are really nasty for 2-7 days and then let up... but with only two tangs and one new tang being his primary focus a lot of damage can be done and that period may be longer. Too many factors to be sure, but that's not a low risk proposition. "Sumping" the yellow when you add the convict may help, as might an acclimation box as you said.

I think it'll work well as a group. Tiny hippo are very good at hiding and for some reason seem immune to bullying in addition by other tangs. It seems no one goes after them in most cases, not sure why.

Hey im thinking of adding some new fish. I have a 9 inch panther grouper. What is a good fish that he wont eat? Hes also with an adult yellow tang and an 11" orange spot rabbitfish.

Anything that won't fit in his mouth-- panther aren't very aggressive but things that don't look they'll fit in his mouth, will.

I am glad it helped! Thanks for the kind words.

As long as you have the real estate for all of those fish (IMO an 8 foot tank) I think it could work. Adding trios of acanthurus works better than 2, and 4 works better than 3. It's not AS effective, but it can still be quite effective depending on species. Clown and powder blue are both very aggressive but different enough in shape I've mixed them successfully before.

I'd select smaller clown tang, and a powder blue just slightly larger, and make sure the Naso (I assume "tank boss") is considerably larger than they are. They act as nice referees when they can intimidate by size, as Naso are quite passive in nature -- typically.

How would a small clown tang do being introduced to an existing 200 gallon system with three established zebrasoma 3-4”?

I know clowns can be terrors, but in this scenario is it not a bad idea? Or is it best to stay away from clowns?

They grow so large and somewhat quickly, aggression seemingly exponentially growing as they grow inch by inch. A small one might be OK for a while but the incumbent tangs will have only one target which is a risk for the new tang.

So what would you think then? Let's say I keep the powder brown (japonicus) and trigger. Do you think I'd be best off adding other acanthurus with those two? Maybe just a powder brown and powder blue, or powder brown and clown? Sounds like the PBT and clown combo may concern you?

Also, FYI--its a 220 gallon which is set up with a lot of swimming room. So, only 6 foot, if that substantially affects your opinion.

Thanks again for your time and help!

The combo doesn't concern me that much, a powder brown and powder blue can be dicey to add together. I've done it, but I'd say the clown is better odds. I'd say two dissimilar acanthurus and perhaps something else added might work.

Ok so let's say we do powder brown and clown and blue jaw all at once. Do you like that for a final intro? Would you think we'd see better odds of success if we add in an Atlantic blue or another Cteno tang as well...?

More tangs would likely reduce aggression, but your plan may well work. It depends on your nutrient export if your tank can handle such an addition to bioload (I overstock my tanks lol)
