Sterbai corydoras.

Postby cobden28 » Sun Jun 10, 2012 9:13 pm

Could forum members please give me some information about the possible spawning behaviour of corydoras catfish, in particular Sterbai cories?

I have four Sterbai in a 4 ft community tank, and within the past day or so I've noticed strange behaviour from a couple of them. Basically, the two Sterbai in question seem to be sidling up to one another with the slightly smaller one of the two almost wriggling to get closer to the larger one - is this spawning behaviour?

The behaviour I describe takes place towards the front of the tank, near to a flat stone.

If it is spawning behaviour, what's the likelihood of my being able to raise any fry in a community tank? Unfortunately I don't have a spare tank available to raise any fry.

Very little chance of raising fry in a community tank. If the eggs don't get eaten, the fry will.
They will nudge each other and the male will "T-bone" the female to get her to spawn. Sounds like yours are keen, possibly 2 males following a female.
They lay their sticky eggs on the glass, usually just above the substrate. These can be removed with a sharp razorblade and hatched separately.
If you want to try and breed them specifically, put them in a separate tank then forget about them. The water will go green and they will spawn. A large, slightly cooler water change will often trigger spawning.

It doesn't have to be a large tank - 18" x 12 x 12 would be big enough :wink:
It might even fit beneath your current tank and hardly be noticed! :mrgreen:

You could get one of those little breeding nets or tubs that go inside your main tank.

They attach their sticky eggs to the glass. I doubt they would like netting. A breeding box would not be large enough

Sorry, I just meant for fry to live in. You mentioned removing the eggs, could you not put the eggs/fry in a breeding box?

Possibly but if separated, I think they need treating with meth blue so they don't fngus so a breeding box would not be suitable.
