Please critique.

Sorry I missed this.. Let me give it a try..

It is hard to get a good assessment, because he is positioned pretty oddly in the picture, but he is a double ray, with about the minimum 33% web reduction required. Except for the wide spacing in the webbing at one point, the tail is pretty consistent throughout.

The same reduction goes through the anal fin as well, which doesn't seem to be too long. Though the front end of the anal does sweep forward, something I like to see, the webbing and rays, at least in this picture, sweeps back, which makes it somewhat odd looking.

The dorsal is the most amazing thing about this fish.
He has a nice broad dorsal base, but his dorsal web reduction is about 50%, and there are shortened rays which detracts from the look of the fish and his over all symmetry.

He has the typical CT body which means he is a little on the thin side for my personal tastes but well within the accepted norm.

His color is good, being fairly consistent thought his anal and caudal, but lacking in the dorsal, which is not good, as the color should be on all three unpaired fins. Also, I would love to see more color on the tail.

One thing though stood out to me, this fish has no vents. At a show, I would have to disqualify him.

Thanks. I think he's a dt geno crowntail because his dorsal is almost equal to his anal fin and I never noticed the missing vents when I bought him but I hope it's not genetic. He was from a petsmart so he was obviously raised in horrible conditions which is why I have the hardest time trying to breed him. he is actually a marble because his coloration has completely changed and now the redness darkened to a purplish color and is on his dorsal. I really wish I could send another picture but now his finnage his horrible and frayed from finrot. Right now the best thing I can do is breed him to my plat female.

He just spawned with my platinum female so luckily I won't have to wait and the fry are just gonna be awesome. Al says all his bettas carry DT and this plat's from Al so hopefully there'll be pastel dtcts, dts, dthms and whatever, the finnage should be bigger and with more branching so the problem with his reduction thingy? will be solved btw what is web reduction? I'm actually surprised he spawned and blew a bubblenest this quickly. This is the first successful spawn I've had from him and hopefully the fry will survive.

Webbing is the membrane between the rays of the fins.
People think the crowning is caused by extended rays, and in some cases, that is so, but I think that may only be so with the CTPKs.
With the long finned CT, the crowning is caused by the membrane, not extending to the tips of the rays, lessening of the webbing is called web reduction.

I'm just so excited because he obviously has marble in him and he is a pastel as well I think and he spawns with a platinum hm so it shouldn't really help with the web reduction but the copper would enhance the purplish color and there would be more opaque. In the F1 the bettas would be halfsuns or superdelta cts and by F3-F4 I should get some crowntails. The female has 4 ray branching so the ct would end up with three ray branchings which isn't bad. Correct me if I'm wrong.

Everything is likely, but for this part..

It doesn't quite work like that.
The tail wants to branch evenly, so you will see 1 ray, 2 rays, 4 rays, 8 rays, 16 rays, 32 rays, and that is how it is supposed to go, however, most fish do not branch evenly, so you will see with a 4 ray, sometimes a 5 or 6 ray area, though the rest of the tail is 4 ray, or an 8 ray may have here and there 10 rays.
Breeding 2 rays to 4 rays is going to give you fish that are 2-4 ray, POSSIBLY, depending on what is on his background, up to 6 rays.
I say that, because a 4 ray female who comes from a line of females with 8 rays will likely have fry with at least 4 rays, and probably more, depending on who she is bred to. The point being that though she only expresses 4 rays, she carried the genetics for more, and then depending on what the male carries, you can actually increase branching.
Now, though he is only a double ray, if he were from ddr breeding, he COULD produce 4 ray fry, and I know Al's stuff, so SHE likely carries 8 ray branching, so it is POSSIBLE to get more than 2 rays on HM, though I will be honest, most CTs look better as 2 rays.
As for tail type, you are going to want to look for rounded edges, they are likely when doing CT crosses. depending on what is hiding in her, I think you'll get long finned fry with some combing, with up to 6 rays possibly 8 on some males.
This is best case scenario.

What can expect by breeding brother to sister two or three generations? Will they become good Cts with 4 rays? Yeah the female was from Al and his fish are HM stock so I was thinking that because the female has 4 ray branching it would pass to the offspring and the male CT has few rays but the female has a lot so maybe the fry will be more balanced.

I'll be honest.. I have not seen many 4 ray CTs that look good.
Their rays seem crowded, and mushed together. I much prefer 2 rays CTs. They look cleaner to me, somehow.

If 4 rays is what you are breeding for, then that is what you are going to get. Just as a reminder, don't look for ray count alone, look for the over all balance of the fish when choosing your breeding stock.

To be honest all I want is for the fry to have big finnage. The original male had a tale that only opened to 60 degrees I want the fry to have a tail span of aroung100-180 degrees which should be very probable since the female is a halfmoon. I agrees, many 4 ray crowntails look very messy. The overall balance should turn out well because this male has even ray branches and webbing and the female as well. And he may very well carry dt which makes it more balanced. Anywyas thankyou for critiquing him and giving me advice. :clap

Well he died but I still have a couple fry from him so I stuck them in a ten gallon tank and hopefully they will survive.

I am sorry to hear that. But you do have some fry, so hopefully, you will get a few that are what you are looking for, or who at least take you closer to that goal.

Yeah thanks. It was really sad cuz he was a blue pastel marble and I'm pretty sure of it because the pic I posted was from four months ago and two weeks ago he lost all his red and became purplish, then he changed to a blue color and he was pretty active and then just suddenly died. Well hopefully the fry will survive and I'll just spawn them to one of the female plats. Thanks for your help and support. :thankssign

All those color changes are certainly the mark of the marble gene, lol. I am pretty sure he was a marble as well.

Yeah . I bet he had red loss too. Hopefully the fry will be just like him.
