Wow! How long's a piece of string? tongue.gif

There isn't s simple answer, I'm afraid. Some species - my C. aeneus sp Colombia, for example - are mature at seven months. Others take well over a year. That said, there are some species that spawn fairly readily, such as C. aeneus, C. paleatus, C. panda and Scleromystax barbatus, so it's those you might want to look at. All except panda spawn on the glass. Pandas place their eggs on leaves from plants like Anubias but a friend's spawned them using plastic plants.

Current isn't always neccesary. I've recently spawned Scleromystax prionotos and Corydoras nattereri and both put their eggs as far away from the filter outlet as possible, prionotos using the glass and nattereri using Java moss to place their eggs.

Feed a varied, good quality diet. I feed TetraMin or Aquarian flake as the staple food. I also use JMC high-protein granules, Tetra Prima and Tabimin. When I want to get the females to roe up I feed white worm or grindal worm regularly - up to once a day - and add occasional frozen bloodworm for a change.

Barbatus and paleatus like it cool - mine breed at 72F and others breed them cooler. My pandas, prionotos and nattereri like the mid-seventies.

I like to keep my corys in at least trios, wherever possible, and a half-dozen is better. You don't need that many for spawning but I firmly believe that they do better, generally, in larger groups.

Hatching the eggs separately is up to you, really. Some species don't bother with the fry, such as Aspidoras C119, but most will eat any they find. I use ice-cream tubs and Tupperware-style food containers. I add an air stone an a clump of Java moss to be a source of micro-organisms for the fry and to absorb some of the nitrates from the water. Once the fry are free swimming I change about 60% of the water for water from their parents' tank once a day. By a month, when they start to look like little corys, I move them to a tank to grow on.

Hope this helps,
Keith

I used to float the tubs in the tanks but lost quite a few spawns when they overbalanced and everything ended up in the tank. I now put them on top of condensation-trap, most of the tanks in my fish house having the lights mounted on the framework so having no hood. The room is heated by a combination of the lights, the few heated tanks and a wall heater so the fry do see temperature changes over a 24 hour cycle but nothing very severe.

I hope your girlfriend is as dedicated as you are because she's going to end up harvesting the eggs and looking after the fry more often than not, I suspect!

No doubt keith smile.gif ive managed to get her more into the hobby herself as her total experience in fish keeping b4 was her 4 year old goldy. now she's got a 2ft tank with mollies,frogs and white cloud minnows given pride of place in her lounge.Over the last year she's been in daily feeding and catching fry from the livebearers so i think/hope we'll be ok.i'll keep you all posted as to my way forward.
