Tangs in a 90g

Recommended Posts

I'm planning on having the following tangs in my 90g:

 

1 Sailfin tang (Zebrasoma desjardinii)

1 Powder Blue Tang (Acanthurus leucosternon)

1 Yellow Tang (Zebrasoma flavescens)

1 Blue Eye Kole Tang (Ctenochaetus binotatus)

 

Does anyone see a problem with this(other than the 2 Zebramosas establishing a little dominance)?

2 of the four tangs listed get to be a foot or more.

 

I'm going to have to study up more on tangs - I didn't know any got that big

the sailfin he mentioned reaches 18" full grown. the powder blue gets to about a foot full grown

 

Those are some big centerpiece fish!

4 tangs might be a bit too much but 3 should be fine. I find that it take a while to reach that size of 12" or more maybe they never will.

 

In my 90g, I have 2 tangs, 1 butterfly, 1 angel and it work out great. im planning to add maybe 1 more sometime in the future.

Tangs do grow to be a foot or more, in the ocean. In a tank their growth depends on the size of your tank. A tang in a 180g will grow larger than a tang in a 90g.

 

True, but that isn't to say it is fair to the animal. A fish too big for a tank may stop growing, but its organs usually do not. Usually fish kept in environments that are too small do not reach their full life expectancy.

That explains it!

 

I must have grown up with a lower bedroom ceiling height than my brothers were in, since they both have 6 inches on me.

I'm planning fish for my 96 gall tank and from what I read you should introduce them all at the same time or immediately after a restructure so the well established fish doesn't bully the newbie.

I have to lean towards the 6 foot for the big tangs as well- I have a powder blue and hippo in a 150G high, but it is still a 2x4 box and the powder blue while very healthy is a bit stir crazy after more than 3 years. Ok how do I define stir crazy- he has picked up the habit in the last few months of charging both ends of the tank and spashing water out. I found so much water on the floor and thought where is this leak coming from? But then realized it was just his splashing and had to place a towel on the floor for a while when he was being persistant. The blue Hippo which is the same size does not seem to be worried at all and is very calm. I would say they are both in the 7-8 inch range. The powder blue is calm most of the time- Phase he was going through?

Can anyone say upgrade?

Only if the one in the 90g gets sick and dies before reaching its full size.

I agree. I think the "fish only grow to the size of the tank" idea is a myth spread mostly by people trying to sell fish. A lot of freshwater newbies buy plecos and oscars for their 10-20g tanks thinking the same thing (not that I personally know anyone who has ever done that :blush: ).

Great example. I've seen plecos 3 feet long. Yet, this has never stopped me from buying one, and keeping him until he is too big, and then trading/selling/eating him. I consider that a completely acceptable manner of fishkeeping. Others disagree, to each their own.

Lee - There's always that 1000 gallon tank in the FS/FT forum for you. The PBT would be loving life then!!

 

I've changed direction a little bit. I am now thinking about going with a Powder Brown Tang, Purple Tang, and Kole tang.
