Cory Strebis

[hogan53]

Hello everyone,
I have 3 sterbas i would like to have a go breeding them any tips on sexing and breeding?

 

[geo7x]

do you mean sterbais? well females are generally plumper (its easier to look at them from a birds eye view to see) and i dont know much about breeding but i think feeding live foods such as bloodworm and dropping the water temperature a bit helps, but you should probably wait for someone who has experience of breeding cories to get a proper answer on breeding

 

[Sp3nc3r]

its said to start the breeding process that you could either toss in a few ice cubes

OR

do a big water change and drop the temperature

thats what i heard, not from experience

 

[Xebadir]

Bear in mind that a couple of conditions seem to always be filled by those who sucessfully breed cories: Largish groups ~6 or more seems to be the norm, with a stable tank that they are unstressed in for a long period of time, plus the cories must reach adult size(somewhere around a year old). Also note that arguably Sterbai's are one of the most difficult cories to breed and of those i have heard success from have suceeded in engineering their tank conditions to perfection by tried practice. Another thing is that often they can be put in a breeding mood by other corydoras species breeding.

Hope this helps

I guess you need to make sure that lowering the temp won't adversely affect any other tankmates too...

Also what is the average size of an adult? I assume you don't need to wait till you have had them about a year to be sure...

Thank you for the reply.
The sterbais are a couple of years old. Excuse the spellingon the last post.
Had a go at breeding Odesa Barbs did okay for the first attempt got 8 fry.

Thank you all.

Yes sterbais are one of the harder corys to breed. Assuming you have adults of each sex here it is in a nut shell:

1. Put them into their own tank to spawn. Since they will eat their own eggs you will need to do one of two things when they spawn- remove the parents or remove the eggs to a hatching tank. I prefer to do the latter. The eggs cn be handled an hour after they are laid. Normally softer water is best for sterbais and their eggs.

2. Begin by conditioning the fish. Stuff them on worms for a week or two, live are best but frozen will work. Do not do water changes on the tank. Wait for a storm to be on the way and then do a large water change right before. Use water that is cooler than the tank temps. Hope for the best.
2. a You can tell they are getting spawnerish when they are rolling and tumbling together all over the tank. When you notice this they next step is to watch for eggs which will be stuck to anything and everything.

3. Pull the eggs to a hatching tank which has a heater and and airstone or spone filter in it. Add a dose of methyblu to the water. When you see wigglers, use carbon to remove the methyblu as it can harm fry.

4. You have now reached the hardest part of successfully breeding them, growing out the fry. Be sure you have adequate/prper food for them. There are many foods you can chose from, I have always used cyclop-eeze but live foods are even better. You will need to feed several times/day (4 or mor) and to remove uneaten food shortly after each feeding as it will fould the water.
4.b. Aside from good food they also need clean. clean water. If vacuuming the tank 15-30 minutes after each feeding does not result in removing and replacing 10% of the water daily, then syphon off some so you are changing 10% daily. Rinse the filter sponge at least once a week.

5. Depending on how many fry you have, you will need to move them to a larger tank for further growout. getting them to live past 30 days is the hardest part of successful spawning.

I have had stebais for years and have had them spawn a number of times. They always spawned on their own, i.e. without my setting out to spawn them. I tried a number of time to raise the fry and always had them die w/i 30 days. As a result they became one of the first fish I intentionally set out to spawn since I don't do well with failure. I eventually raised some past 30 days at which point I went on to other things. I have still have a group of 12 which includes 5 proven breeders and someday I may try again with them.

THANKS FOR THAT TWO TANK.
I will have a try, i know they can be difficult to breed,spawn and raise.
Maybe i should have a go at Tiger Barbs instead.


thanks again

From experience this is how i force mine to breed ( this is based on Peppers, Albinos and Bronze's)

I feed them up on nothing that frozen blood worm, and if im feeling generous, i will sling in some pellets from time to time.

I perform a daily 50% water change with cold conditioned water straight from the tap ( or if its not 10 degree cooler than that in the tank, drop some ice cubes in the water to get it down). IMO i wouldnt drop ice cubes straight in the tank and thats because of the next part.

In the wild, corys breed during heavy rainfall, so you need to recreate this and i do this by topping it up with cold water via a jug from about 12" or so above the water line so it splashes around.

Do this for a week and see what happens.

If this doesnt work then you can up the water changes to twice daily.

When they have spawned i remove the eggs to a hatchery and away they go

all this is in my experience and some corys are harder to breed than others.

Good luck mate, and trust me, its VERY rewarding when you see them there wrigglers hatching
