Hello Everyone,

I am a new member just joined the forum. I need your help please.

I have a 120 gallons DT mix reef (2 years old). Currently, I have a yellow tang (about 3.5 inch) and has been in the tank since the beginning, lawn mower blenny, royal basslet and two fire fishes. I like to add a new Gem tang (3 inches) or Purple Tang (2.5"). I prefer to have a Gem Tang. Please let me know if this is an issue with the Yellow Tang.

Thanks

It’s very likely the yellow will not accept either but it’s possible .

You nevet know with tangs of the same a peices. I recently added two yellow tangs at once. I ran them through quarantine together with a section of eggcrate as a divider and I think be able to see each other and interact so to speak but not touch really helped. I added them to my 180g and they are swimming a round like best friends for the last few days. The real test will be when I bring my purple back up. I was able to remove him to timeout in another tank. The yellows are around 4" inches and the purple about 7". It should be interesting.

I used to have a purple and yellow in a 120 and no problem. Now they are in my 210 with other tangs and they are the most well behaved tangs. I have a gem and will stand up when being pushed by the desjardini or by the achilles.

You just never know with tangs. Some get along some don’t
With only 120 gallon it’s iffy.
I have
2 Yellow
1 Scopas
3 Purple
all in the same tank and no problems at all but it’s also 1100 gallon tank

I have Purple Tang, Yellow Tang, Gem Tang, Derjardin Sailfin Tang, Blonde Naso Tang and Powder Blue Tang in my 120G .

All of them are added individually on separate occasions in the above order of listing, using combinations of (1) mirrors, (2) tank separator, (3) multiple nori clips, (4) “sumping” the aggressor for a week and then reintroducing to display with tank separator for another week; so far worked for me.

Also I believe as long as they are well fed, there’s no reason for squabble.

Your best bet would be an acclimation box for the gem or purple tang. Get them used to each other a few weeks.
Keeping a 3" zebrasoma in an acclimation box for a few weeks is straight cruel.

I have a Purple and a Yellow Tang in my 240.
Had a little bit of aggression when I added the Purple, but the mirror trick worked perfectly.

I find it funny the mirror tricks work for so many. I tried putting one up on my 180g just to see and not one fish even paid attention to it. The flowerhorn I used to have sure did tho, he would attack it non stop. Depends on the fish I guess

What are the dimensions of the tank? I’m assuming it’s either a 4’ or 5’ tank.
In a 4’ tank you shouldn’t have multiple tanks and in a 5’ tank even that’s pushing borderline IMHO. If you want multiple tangs in a 5’ tank then you’ll want to stick to tangs of different genera. Ideally only having one Zebrasoma and one Ctenochaetus. Zebrasoma is a much more active genus and I’m sure you’ve seen the activity this genus has just in your yellow (Which is one of the calmer species in the genus).

I really recommend against this, the tangs you want are highly active (as well as anggressive) and chances are higher on them not doing well together.

That is amazing that you would be able to keep that many Tangs in a 120G. Would they outgrow the tank and needed a bigger tank?

My tank is 4', I wish it was 5'

Thanks everyone for your feedback. I think it is about 50/50 (yes/no).

What size of acclimation box you would recommend for a 3" Gem Tang? I will look for one on amazon.

I will try the mirror method as well.
For a 3 inch tang, you really want a large acclimation box (which may take up the majority of the top corner’s room in your 4’ tank).

I would if they are outgrowing it to my holding tanks (4x4x4 or 8x4x4), But for now the sheer numbers and good feed are keeping their aggression in check, also I have just relocated all my corals and rocks, in preparation of COPPER+METRO followed by PRAZI for parasite eradication. Going FOWPVC for the next 3-6 months. Also I may take this opportunity to add White Tail Bristle Tooth, Powder Brown and Achilles Tang.

I have not decided on getting the new purple or gem tang yet. I placed a mirror in of the yellow tang, as soon he saw the mirror he ran and hid behind the rock.

Does this mean yellow tang is not aggressive?

IMHO, YT is the mildest among PT and GT.
