Myah Posted December 2, 2009 Report Share Posted December 2, 2009 Hi all, I have approx. 40 black, black/blue, black/white swordtails. All from the same father but from two mothers (all bought from the same place). The 1st batch are approx. 3mnths old and the males look like normal swordtails but all the males in the second batch ( 2 weeks younger) have a round tail (like a female)with the sword on some just starting to appear and the dorsal fin is crown shaped. I thought it was only 1 or 2 but after watching them, there is about 10 of them like it. Is this a normal type of finnage or could they be deformed. They are quite large in body size compared to the others. Sorry they aren't very clear Quote Link to comment Share on other sites More sharing options...

Sophia Posted December 22, 2009 Report Share Posted December 22, 2009 i have 2 young black swordtail males - I thought they were a rare colour so googled it to see if worth anything and read that black swordtails with black in their fins may not be healthy. here is the link - http://www.aquarticles.com/articles/bre ... words.html some others may have better knowledge but otherwise this might be a bit depressing to read :oops: they are cute fish though 8) Quote Link to comment Share on other sites More sharing options...
livingart Posted December 22, 2009 Report Share Posted December 22, 2009 it will depend if the gene for black in your fish is also one that causes a suseptibility for cancer as well only time will tell Quote Link to comment Share on other sites More sharing options...
Myah Posted December 22, 2009 Author Report Share Posted December 22, 2009 Hi, had read the article about the black finnage being cancerous etc., but it was the actual shape of the top finnage and tails I was looking at which I didn't find anything about in any of the articles. So far, only 1 or 2 of the males' swords have started growing on the second batch, the rest are still roundish tailed like the females, or have a raggidy appearance which looks very similar in all of them. The females are starting to have fry but if it turns out the dads are deformed then I wont even consider saving them from the other fish to sell.

livingart Posted December 22, 2009 Report Share Posted December 22, 2009 most of the newer fin types and body shapes on fish are a deformity from the norm celestial goldfish being a good example Quote Link to comment Share on other sites More sharing options...
