Tubercles - male.

The difference between tubercles and sensory pores is obvious when you know what you are looking for (as you now do), these are clearly tubercles from a sexually mature male

Like you I initially thought that the fish was ill

If you compare your picture with mine you will see ...

You can see the tubercles much easier if you look at the head from above, allthough the picture above is of higher than average quality I cant really see if there are tuberclesas as they tend to be most concentrated on the top of the head. The specimen Ive shown is around 7 inches.

smaller less pronounced bumps are readily visible on the head and are indeed sensory in origin. Think a few of you are confising these with my theory on tubercles. The tubercles are much larger and resemble grains of salt or ich. The 2 are totally different and are NOT related

should be a little more pronounced, almost like ich. Think they are too faint and too few to be tubercles.

Cant help but feel cheated about he way that my paper is being distributed without my consent, thanks guys. lesson learned

I presume so, since it has never been observed before, that is the only conclusion I can come to

The paper is only on artificial fish propagation, not on sex differentiation of clowns

The picture you have shown is either a female or a male which is out of breeding season, otherwise the picture would be of sufficient quality to view tubercles. Is this your own fish? Lovely specimen and great photo if it is. I realise that you have probably looked at lots of pics to find tubercles ...

Mark, the breeding season in most species is at best very breif, maybe a week or so. The photo you have shown is possibly what Martin is being confused with. Martin correctly depicted sensory vesicles on the head which are present at all times. Only my fascination/obsession has discovered a narrow ...

I completed the paper on "artificial propagation of fish species" for my Bsc. In doing so I discovered the potential for its use. The old method which involved direct extraction of hormone from the pituitary gland* was, I thought primitive to say the least and it was counter productive to kill a ...
