sex changes??

[cageman]

hello,

a while ago I read a thread here that had a few things about sex changes.
for example furtile female that has had fry, changes into male and produces ofspring with a female.
I'm interested in these kinds of knowledge.
anything you all know is welcome.

greetings,

cageman

I think that happens in Crenicara. Use the search engine here to find threads on this fish.

There are many sex-change reports in Taiwan and Hong Kong for apistos, examples including Inka50, and Agassizii. All cases show that a female fish which once had fries then transformed to be a male fish (with, at least, the full male fish's characteristics)... i remember i had some old postings discussing this topic, you may wish to take a look. Cheers ^.^

^.^ so, Cageman, do you have some experience to share with us?

[cageman]

no not really, I'm just looking for evidences of these kinds of sex changes.

and if someone knows some scientific publications on this subject, please let me know :)

still couldn't find the thread by the way,...

Koslowski described a true sex change in A. sp. Wangenflecken/Cheek-spots in his 1986 book, "Die Buntbarsche der Neuen Welt - Zwergcichliden". All other reports that I have heard about could not be positively verified because the breeding & sex changes occurred in uncontroled settings.

1. the thread:

2. hmm, i think scientific evidence is quite difficult to obtain because
a. it has to be done in an environment under control.
b. the life of an apisto is quite short, if we have to wait for a mature apisto to
spawn and have fries, then transform to another sex and spawn again, it takes time and many apistos would have already passed away ...

Here is a link to an article that I wrote describing a possible sex change observation in Dicrossus filamentosus.
