Upside down cory ?

[hotsauce48]

Still can't figure out my cories species and don't have the camera,but I saw it spawning today and I noticed it grazing on my marbled queen radican upside down.And the female tiped over the smaller male on his side and started digging in his personal area,is this normal?Because about 2 min. later it gave birth again.Today it gave birth about 6 times.

If by "give birth" you mean "lay eggs" (as in my way of seeing "give birth" doesn't apply to laying of eggs), then I would say what you describe is pretty normal spawning behaviour, the female will often place the eggs under a leaf, and to achieve that, obviously, it need to invert.

that's how they mate, they form a T position with the female , ingestng, the male cories sperm and then it goes thru her system and fertilizes the egg she then lays.

right?

Not sure if I agree to the latter part - may just be how I interpret things: If by ingesting you mean "swalllowing", then I doubt it. The sperm is just spread in the water column and some of the sperm hopefully reaches the eggs. Some sperm may enter the mouth and exit the gills, but certainly no other form of "ingesting" is involved. [Supported by: http://en.wikipedia.org/wiki/Ingest].

yes, I agree, either way. Sperm in the water or ingesting. It says here at PC, this link, scroll to sexing, that it is a much debated area in cories.
