Josh Posted December 14, 2003 Share Posted December 14, 2003 :o I was striping one of female saulosi's today and noticed that one of the fry had two heads! Before any one complians it has already been feed back to the other fish. I was just wondering if this is common, or is it bad breeding stock. I have made the effort to get fish from differnet places. It is the female third spawn and I have never noticed any like this before, nore have any of our other females had this problem. :^:Josh and Evelyn Link to comment Share on other sites More sharing options...
Ben Posted December 14, 2003 Share Posted December 14, 2003 Hi Josh,I have heard of this before. I remember it being posted on the forum with pictures too. Was about three years ago. Can't remember the type of fish.I don't think you would have too much to worry about. Only if you were getting large numbers each spawn. Keep an eye on that female. Next time she spawns see if you get any two headed fry. Link to comment Share on other sites More sharing options...

griffin Posted December 14, 2003 Share Posted December 14, 2003 Two-headed fish are basically examples of conjoined twins (AKA "Siamese" twins, named after the famous twins Chang and Eng). Identical twins form when an early embryo splits into two entities and the two seprate bunches of cells go on to produce two identical animals. With conjoined twins they have started to split but did not split completely so the two twins are still joined together at some point. In the case of your two headed fish, they started splitting down the head but the split didn't get any further.I would think this would just be a freakish occurence - happens occasionally in other species (there are a few 2-headed turtles and snakes in existence) and I wouldn't expect that the female would continue to produce such fry. It's not likely to be a genetic problem, it's a mistake in development.HTHCheers,Jess Link to comment Share on other sites More sharing options...
YeW Posted December 14, 2003 Share Posted December 14, 2003 It is a siamese twin.I'd recommend culling it. It isn't a nice way to live. Link to comment Share on other sites More sharing options...
Michael Posted December 14, 2003 Share Posted December 14, 2003 Hinez is Melbourne that owns All Aquarium has Siamese twins. I think they have been alive for 10 months now...Dr Harry came also and seen them. Link to comment Share on other sites More sharing options...

23Skidoo Posted December 15, 2003 Share Posted December 15, 2003 I'd like to do some experiments with fish in this condition, regarding dominance (which head rules) and also mate selection experiments, to see if their form is accepted or not, if anyone else gets fry like this in the near future (next coupla months) i'd be happy to come and get them from you.
