Swordtail pairs  If you order one that contains Hi-Fin, only one of the pair will have the Hi-Fin. The other will be Standard. In double dose, Hi-Fin is a lethal gene, so it's always best to cross a Hi-Fin with a Standard.

The swordtail fish that we ship are between 3 and 8 months old.

We are many years into this project.  The goal was to increase size and vigor in domestic swordtail fish.  (see project outline in our Blog).  We crossed 2 wild Xiphophorus species into a domestic line and then separated the offspring into various strains by color. We then selectively bred for size and traits that we like and have been amazed at the size we are obtaining at this stage. By far the largest adult swordtail fish we've ever seen - simply magnificent fish.  These fish may carry other genes, like hi-fin, various albino combinations,  patterns like Koi, Neon, Green, White and maybe even others, so getting a few varieties in the offspring is common.

The Tuxedo swordtail type was developed from both wild fish and Red Alpha swordtail strains. The color is orange, not red, though some of the offspring will be more reddish than others, so you can select for that. Video showing some of the Tuxedo swordtail strain below:

The below video is an example of swordtails and angelfish getting along fine together. There is never any interaction between the two.

Ruby Red Swordtails - We are now offering the ruby red sword, which has the color in all its fins and it tends to be more intense than any other swordtail.


Piebald Swordtails: This is a rarely seen variety. They are a combination of a bluish-grey and reddish-orange color, randomly distributed on the body. This piebald trait gives great variety in the expression of these colors.

Pair of red brick

Received my pair of red brick yesterday. I am impressed by their body size and color, especially the male swordtail. He is a wild monster!

Red Brick Swords

Excellent quality. Male's swords not fully developed but have large bodies for sword development stage which indicates large bodies at maturity.

A pleasant surprise!

The angelfish and the tuxedo swordtails arrived in perfect condition and all were beautiful. But the swordtails were spectacular!! We do not see swordtails like this at stores in NYC anymore! They are well worth the price. Can you offer them for sale as trios?

Good Quality Red Bricks

I ordered 4 pairs of the "red bricks", not expecting to get the original, now virtually extinct, strain, but hoping for good quality, robust fish. I wasn't disappointed. I'm especially pleased with 2 of the males, as they're very robust, high-shouldered fish that haven't even fully matured. Once full grown, those 2 males will be huge! I believe that one of the wild Xiphophorus species crossed into this line is X. mayae, which would explain the size.

These are the most vigorous swords I've ever had. Also the biggest!
