This is my final stand! I want to succed in breeding Cories of any type. What types have been bred or are the easiest to do so? I have a 10 gallon that i will use, do i need sand or is a thin layer of gravel on the bottom? Also I always had a hard time to sex them, also what is a good breeding medium?

The females are wider than the males when you look at them from the top & both fine gravel & sand are fine for them. I would get 2 females & 4 males & the easiest are the Bronze Corydoras. Feed them well with a varied diet & protein food. Do a water change in the early evening & add colder water in your tank. This should trigger them to breed & they will lay some eggs on the glass during the night.

Do not breed aeneus in a ten gallon-at least not six of them.

I would do Hasbrosus or Hastatus Corys,
or maybe julliis or trilineatus, or ambiacus.
They are all very nice and could fit a breeding group
in a 10g.
Aeneus Corys I agree, too big for a 10g.

Corydoras aeneus and Corydoras paleatus are the two easiest species to breed. However, they are also the two largest Corydoras species. If you want to breed them in a ten gallon tank, you will have to limit yourself to a single pair or trio of breeders.
Other reasonably easy-to-breed cories include C. panda (easy to spawn, but the fry can be difficult to raise), C. metae, C. adolfoi, and C. trilineatus. These latter cories are smaller than the first two, and a shoal of any of these will fit in the ten gallon.

Gravel would be fine on the bottom. Cories are easily sexed, in that females are broader and fatter than males when mature. Also, females in most species are longer than the male cories.

Cories will usually lay their eggs on either the aquarium glass, or on plants. All types of plants from java moss to broad-leaved Amazon swords can be used, but the best are those that allow flat space for the female(s) to plaster her eggs.

I would try the Juliis, but for sure thay are more difficult to breed than the Bronze Corydoras.

Trilineatus are quite easy to breed, IMO. I have had no problems finding their fry when cleaning the 75 back when I kept them, though the fry were admittedly fragile. As of now, I only stock sterbai.

Just as a note, any "julii" cories you see up there are probably false juliis, Corydoras trilineatus. Again, they're fairly easy to spawn and breed, they just need to be healthy and well-fed. Large water changes often trigger spawning with mature specimens. The toughest part about breeding these fish is the wait for them to actually reach sexual maturity, since most C. trilineatus sold in stores are only two or three cm long.

I tried to breed my Bronze cories before but I did'nt succed. I thought i seen them do the whole t postion mating dance but i did'nt see any eggs. Id like to try and breed them in something like a 3 gallon to find out if i actually have a pair or not. They are now in my 30 gallon getting fed flakes and shrimp pellets.

Cories don't form pairs and a 3 gallon is far too small for even one bronze.

The largest ones hit around eight cm in size. Those would be the females, males top out at seven or so.
