So, why can't we breed tangs?

I think yellow tangs would be a good place to start. I know they have spawned in captivity, but what is the burdens involved in raising the fry?

Lets try to think up some ideas to help propagate the multiple species and genus of tangs in order to help reduce wild collection.
 
I like your thoughts and this def not a new issue,,, As you prob know that it requires alot of water and a really tall tank of some sort. I really think to get something like this off the ground a group of breeders are going to have to get together and work this project together because of the startup cost of this,,, I really think that it will happen within two years for a breeder outside of a lab to add to the notches in his/her belt

I'm in the process of securing venture capital for a saltwater fish breeding company.

I have two ultimate goals:

1) To breed surgeonfish
2) To create hyrbrids of dwarf angelfish, such as potters x loricua
 
1. The size tank required to spawn.
2. The larval period is very lengthy
3. Differentiating males and females
4. Necessary triggers to spawn


From some of the reading I have done the tank required to get them to spawn needs to be larger than most any home breeder could supply. Many feet vertically at a minimum due to the nature of the spawning behaviors. This has been seen in large public aquariums.

The larvae have a lengthly period drifting so that creates other issue with filtration and feeding.

Sure it could be done unfortunately the catalyst and $$$ doesnt exsist because a fisherman in hawaii can snag one out of the water for a couple bucks. When the economics of the hobby change things like this will start to happen.
 
How many feet are we talking in tank height? Also, I've heard reports of tangs spawning in home aquariums.

I know it isn't really worth the money for species such as zebrasoma flavescens, but imagine captive bred z. rostratum or z. gemmatum.

If they DO spawn and the eggs DO hatch, what would the fry eat?
 
I would like to see a report on home spawning. I have seen reports in public aquariums but not sure of the heights. If I had to guess 6-8ft minimum but that is a complete guess.

There are captive raised hippos in the world and I'm sure some research on them might lead to some food ideas. Rotifers seem like a first food for many larval marine fish. But the whole process would be observation, trial, and error.

Rotifers are too large. If it was that easy, tangs would have been captive bred all ready. There has been no blue hippo tangs captive bred, only post larval collected and "tank raised".
 
It all boils down to economics in the end. We probably have the technology to mass produce them in captivity, but is it economically viable?
 
We don't have the technology, sorry :) There are many with big $$$ that would pay $$$ to get one, yet there aren't any around despite global efforts to produce them. They are the Holly Grail of MO fish breeding ;)

I disagree. Someone with a big budget who wanted to spend millions on a facility could do it, but it wouldn't make financial sense - not when you can go out and haul in yellow tangs by the net full.
 
The video is pretty sweet and that video was shot in a store not to far from where I am. Wonder who bought the pair.

One thing I did not see in the video was a release of eggs or sperm. Cool nonetheless.
 
Sustainable Aquatics, Knoxville Tn currently breeds Yellow Tangs and Blue Hippo Tangs For sale to LFS In our area and Is second only to ORA at breeding Fish for the moment!
