Hello yes I have some questions about breeding danios... ok so I was wondering on how hard would it be to breed Giant Danios with other smaller danios? Please and Thank You.

Are you talking about cross-breeding or breeding two Giant Danios with other danios in the tank?

If you're talking about cross-breeding...it just ain't gonna happen. Sorry. Not sure why you'd want to, anyway.

As far as breeding Giant Danios, it's not hard. If you give them good water conditions, it'll probably happen naturally. Just don't expect a high survival rate, especially in a community tank. Most, if not all, of the eggs will be eaten before they hit the gravel. Any fry that do hatch have a decent chance of being eaten. If you're going to breed with any success, you have to isolate a pair in their own tank with some sort of largish substrate (like marbles) for the eggs to fall into to avoid being eaten. After the eggs are laid, remove the adults.

Edit: Hah! I beat you, Shini!

Hello, welcome to FishProfiles.

It is, as far as I know, impossible for Giant Danios to breed with the smaller species of danios. They are too distantly related. Even the species of danios within the genus Danio do not hybridize with each other, so I would not expect a good chance for a member of the genus Devario to hybridize with a Danio species.

Oh alright then cause I was planning on trying to breed the glofish (a modified zebra danio) with a giant danio to produce a giant glo... And also thank you for your advice! It will be very helpful.

I'd say trying to breed those two would be almost impossible but using marbles is the best way for danios
