Hello,

I'm wondering what Angel I have here..? 75% sure she's female, but obviously this isn't guaranteed till spawning!
She has some blue on her but its hard to catch this on the camera! Sad
Thanks! Smile

Sometimes, without doing a test cross, it's hard to be absolutely sure what you have.
At first glance it looks to be a silver, but there's something going on at the rear, there's odd marks at the top of the anal fin & rear of the dorsal fin, which could be down to some sort of marble gene, but I suspect, when you take the darker than normal tail and the darkness between the tail band & rear body band into consideration, it may be an incompletely expressing half black.

Half black is a slightly problematic variety in that it results from a recessive gene, but environmental, and possibly other genetic influences too, cause a fish that's genetically half black to develop as a normal silver, or only partially express.

A fully expressed half black looks like this :-

Thank you very much. I wasn't ever sure if it was a Half Black or Silver! As you say, both her anal & dorsal fins are slightly off in coloration!

Thanks again! Smile

Of course, the Half Black and Wild Silver traits aren't mutually exclusive, so it's not one or the other, but likely a combination of both: a Silver Half Black, which genetics calculators tend to describe as just 'Half Black'.

Personally, I think Wild Half Black is more descriptive Laughing

obviously wildreddeer is the man for sexing accurately but I keep looking at the first photo and can't help thinking it looks like a male to me. There looks to be the beginnings of a nuchal hump growing Neutral

Hard to tell, but following visual guidelines I came to the same conclusion Akasha, that it's a male angelfish.

Knowing nothing about the parents, broadly speaking, there's a 12.5% chance ( 1 in 8 ) it's a male and homozygous halfblack.

Hi and welcome,

Sorry if I'm the tiding of bad news but you have a fine looking male there.

http://www.uk-angelfishforum.org.uk/t417-how-to-sex-your-angelfish.

Is where I have posted guidance for sexing Angels. It might seem a bit complicated at first but give it time and you will find it very straight forward.

You won't see much of me on the forum, as due to health I had to pack it all in. But I just can't let it go. So hence I'm still around.

Good luck with your Angels.

Phil.
