two headed fry

[Raf]

Hi all,

Today I discovered in a batch of newly hatched S. boitonei a two-headed fry.
Anyone has any experience with this and survival chances of these little monsters?

regards,

Raf

Hi Raf, I also found a two-headed fry once from a batch of magnificus eggs that a friend passed to me recently. I was quite shocked at first but found it to be quite special in its own way. Unfortunately it did not survive. I tried to preserve the tiny body of the fry but it disintegrated very quickly.

The fry usually does not survive beyond the hatching stage. With two heads it will have a problem feeding. I believe such anomalies happen from time to time.

I've manage to keep them alive for a week but after that they'll die. I don't think anyone has ever raise it to adult.

hmmm a double-headed killie fry...

So far for apistos, havent seen anything like tat
Thank goodness

but for a double-headed killie...its very pitiful....
It suffers so much


Anyway for 'double-headed snake' this phrase,
Isit possible in real life? What about other animals?
Quite curious about this

Sorry for going off-topic a little

Yes there have been double headed snakes and turtles. One story mentions a two headed kingsnake which self destructed when one head tried to devour the other and both perished.

Here's one of my deformed Aust. nigripinnis:

Hi Guys,

Have being a while since my last post. Now back to work...

I've recently hatched a tray to Nothobranchius rachovii MOZ 99/9 and I saw a 2 headed fry.



Any comments on this?

The fry has one body but with 2 heads. In the past, I usually see 2 fry that are attached together at the belly. This is my first encounter. The eggs were sent to me by a hobbyists in Brasil.

Off with its head!

This is a developmental quirk. The fry will perish and that will be the end of it. The eggs no doubt traveled a long way and the development of the fry may of been disturbed along the way. The result: 2 heads.

Hi Au,

I doubt that your fry will survive. I tried it with my S. boitonei fry and it died after 4 days. Like Tyrone mentioned, it seems like it is a result of a disturbance during the development (maybe temperature shift?) as the eggs I received were sent to me from France and more important: from the European winter to the South American summer.

best regards,

Raf

These 'conjoined twins' are caused by either a hereditary defect or some environmental pressures. It happens from time to time.

Extra limbs appeared in some frogs that were exposed to some sort of pollution in the water.

They usually don't survive. The only two headed animals I can think of and which survive, are two-headed snakes and two-headed turtles.
