Captive Breeding

[herpchat]

I was asked the same thing and have no clue.

Could use the general fishkeeping rule. Females are more plump and look for slight distension of the abdominal area.

That's the bad part about marine fish. Most can't be sexed by outward appearance. Besides size, there isn't much of a difference in clownfish. Heck, there are even some fish that freely go between male and female. To "answer" your question, I don't believe you can tell. You might want to ask Dr. Frank Marini.

Oh I know that one. If you could get juvies and raise them up together two might pair off.

I did read how to sex gobies, but that is the only normal marine fish I know about sexing on.

At least ponies are easy.

OH Cardinal fish can be sexed by jaw shape.

 

[captbunzo]

Where did you find that information about Cardinals?

 

[Travis L. Stevens]

It states here that it is useful, but is not always acceptable. Jawshape in Pterapogon kaudnerni changes from time to time. http://www.raingarden.us/banggaimanual.pdf

Mouthbrooding fish tend to be sexually dimorphic

Update for the breeders out there

Update for the breeders out there

I've stopped raising larvae a while ago, but the successful clutches are getting a bit larger. I was playing around with some 50mm lenses and here are some of the pics. They are around 4-5month old juvis.

The first one is of the youngest batch. I had many more survive in that one.
The middle pic is of the oldest juvis.
All are percs btw that's why they seem to be taking forever to grow bigger.

Its so cool to me that even as such small babies, the saltwater fish are just as colorful as the adults. Whereas the baby freshwater fish in cichlids I have kept start out plain and color up as they grow.

 

[herpchat]

Depends on the fish, there are a number of juvies just as colorful as adults, Pseudotropheus demasoni for example.

Kevin,

How about bringing some of those clowns to a meeting and selling them?

Or better yet, I come to your place and pick some up.

Ever get one with a "lucky" fin?

OK here Goes;

In mouthbrooders the jaw swells while holding, after holding is complete the jaw goes back down to almost normal but never gets totally normal. It still is usually dimorphic if you know how to look. This can be very subtile.

The absolute master at sexing fish is Kenjiro Tanaka. He can sex a wild betta at 1/4 and has a 100% accuracy rate.

I have a question, kinda off subject, but not really, but how do you tell a yellow tail damsel male from a female apart?!...

I actually looked it up and found what might be a true answer, if so I might want to try them;

http://animal-world.com/encyclo/marine/damsels/devilfish.php

According to this only the males have yellow tails and the females remain blue but develop a black dot.

Kevin,

Those pictures are neat. It must be fascinating just to watch a clutch of juvenile percs swim around in the tank!
Keep us posted...

Gerald,

Those pictures appear to be of the fijian blue damsel. Not the standard blue damsel with yellow tail. Those have more of a golden orange color.

Beautiful fish tho, one of my favorites.

 

[pwhitby]

compare these pics with that posted by Ray in his thread Yellow tail damsel. Thats the common yellow tail.

Has anyone seen this?

I just bought it so I guess when it comes in I will see if it is any good.

Well I gave it a shot, I figured since I had the same question I would look it up, tis why I stated something like I think its correct. I guess it was not correct. So how can you sex damselfish?

Better Question, how do you sex chromis?

Im sorry....but welcome to the issues of saltwater. What you just inadvertantly showed was the difficulty of simple things such as nomenclature. For example, a yellow wrasse acn be one of several species. Thats compounded by a lack of binomial nomenclature among hobbiests. In part this comes from the drive to have show tanks when saltwater systems became popular. Whereas a lot of FW people were enthusiasts and into active breeding programs. Remember, saltwater is relatively new by comparison with FW.

Anyway...my point was, even when given information, it just may not apply. From now on, you are in uncharted territory (good luck by the way).

And....as a final note....I would much rather you tried to breed fijian blue devils than plain old yellow tailed damsels.

Actually...as another side note, why not try Anthias. They are sexually dimorphic, relatively easy to keep, shoaling, non territorial and tend not to require huge tanks.

Just a thought.
