Self fertilization????

[marblesojecki]

I have a cardinal (single fish) that just laid eggs (spawned? - or is that with two fish?) and is now incubating them in her mouth. First question. Why is she laying eggs when there is no other cardinal in the tank? Second. Why does she have them in her mouth if she laid them? I thought the males did that. Third. Is she a she? Final question. Is there a remote possibility that they will develop? Any info would be grealy appreciated.
Thanks

what type of cardinal?
yes the females lay the eggs and the males carry. It has been reported in captivity that a female wil pickup her UNfertilized eggs and carry them. The eggs will terminate after a day or so, so no worries- she will not carry for long.
Yes she is a she, males don't makes eggs.
Highly unlikely w/o a male or another fish around that they will be fertile eggs. Actually shy of a few frogs there is NO parthenogensis from fish.
