Brood tail and butterfly tail

[goldfishin]

I need to know the difference between the butterfly tail and the brood tail. I haven't found a site that has the different tail types. Any help from you fish keepers?!

That's a good article with nice photos. It does get a little confusing. I think broad tail is almost the same as a veil tail, with just a slight indent or fork. Butterflies and tosas are generally not forked either, but their curtains are hung differently. Their lower lobes are spread so far apart they are nearly horizontal out to the sides, then they also spread forward. ......This is nearly useless without photos...... I wanted to say I bought fish sold as butterflies because that's what their parents were. They actually had fantails. Forked tails that go down and make an upside down v ^. Their babies were fantails, butterfly tails, and veiltails. (save the ones whose tails are horizontal and in a few months they can't swim.)

Broadtail is a side-view type. Butterfly is a top-view type.

Butterfly and tosa tails are so flat that you do not see much of anything when viewed from the side. It is like looking at a flat sheet of paper from the side. They were not designed for the aquarium but look great in a tosakin bowl or tub.

When they wiggle that flat tail back and fourth they do not get any traction to propel them. That's why all butterfly tail telescopes and tosakin are poor swimmers. If the tail is angled upward or downward then they not only swim poorly, they turn somersaults when they try to swim fast. Head-over-tail somersaults if the tail angles up, and tail-over-head somersaults if the tail angles down

Now imagine a sheet of paper which is folded. When viewed from the side, the folds give the sheet of paper form. Hence, the side-view tail.

As butterfly tails have become more popular the breeders have stretched the limits of what constitutes a butterfly tail. In my opinion, if you want to call it a butterfly tail then the shape should be reminiscent of a butterfly. There needs to be a new name for these top-view telescopes whose tails do not look like butterflys.

Norm, if 5-10% of the offspring have butterfly tails (that really look like butterflys) then you are doing very well.

Now that is the info I was looking for! Thanks all. I bought 10 butterfly tail moors last year. I could not get a male to do his job so I spawned a female to a very nice black moor I have. The spawn is 3 weeks old and I can see veils, some with the wide flat tail, butterfly tail and some with the fan tail. I got a few single tails in the bunch too. This is interesting to me.
