Tools to better succeed in hatching Corydoras in the fishroom.

[@ljsshrimp]

hmmm I actually have a coffee filter basket I about 2in diameter circle covered in that really fine mesh. I bet I would work to make one.

[@mrbaquatics1120]

I bet you could definitely come up with something!

I just came across this because i've had the exact same results as you using the Fluval breeder boxes and just found out about the German Breeding Rings. I have been hatching my Corydoras eggs in Tupperware containers, then changing water in them every day. I'll have to try the rings. At what age do you normally put the Corydoras fry in the Fluval breeder box?

[@mrbaquatics1120]

Hello, thanks for the view! I usually move them over when the are outgrowing the ring. If it’s a small spawn, that could be a month to 6 weeks. A larger spawn would be moved over in about 2-3 weeks. The longer you can keep them in the ring the better as the smaller container allows them to find food easier helping to increase the number of fry who survive. I hope this helps and answers your question.

Absolutely does, thanks.

Thank you for sharing your experience

Thank you my friend! It is my pleasure.

I love methylene blue. My cory catfish eggs are transferred to a 24 ounce plastic water cup with 2 dabs of methylene blue. A dab is not a drop. Get some methylene blue on the end of your dropper and just touch the surface once or twice. Looking for just beyond sky blue once mixed in. Add a small airstone and 4-5 days later every single egg hatches if fertile.

Thank you for the tip! I may have been using too much! Never to late to learn!

Is that hydra at the end of your video? Do you have any problems with the hydra killing any of the fry?

[@mrbaquatics1120]

I do have Hydra in tanks where I feed bbs. Usually, it's not a problem. I just remove them from glass, and the adults eat them. With tanks of young fry, I do try to limit the feeding of bbs. You are correct in guessing it could present an issue. I have not witnessed it personally, but it could happen. I'll be addressing hydra in a future topic. Thanks for the comment and the idea for a video!

Sera Mycopur works as well as antifungal

[@mrbaquatics1120]

I've not heard of that one. I do like Sera products, so I'll have to look for it and give it a try! Thanks for the tip!

[@donengle1220]

Really good info. Thanks. How long do you keep your fry in the Feeder box? I have some about a week old. I have a shrimp tank that is cycled and waiting for them.

[@mrbaquatics1120]

Hey Don! I usually keep them in breeder box for about 3-4 weeks as long as it’s not over crowded. Adding an Indian almond leaf into the box allows them to have some cover as well as helps grow bio film so they have a constant food source. Thanks for watching! Keep me posted on how they are coming along!

@@mrbaquatics1120 do cories eat bio film?

[@mrbaquatics1120]

@@pauledwards5607 yes Paul, when young they will eat it off of botanicals and even mosses. As they get older they will more likely be eating small organisms living on your filter and glass which feed off of the biofilm there.

[@frogs..fishmore5669]

Hi ... What size is the German Breeding ring that you use ?

[@mrbaquatics1120]

Hello! Thanks for the question, I use the 4 inch GBR for catfish. I believe it is $31.

Will Corydoras eat their own eggs?

[@mrbaquatics1120]

Cory will definitely eat eggs if the come accross them in the tank. Your best option if you want to try to raise the fry is pulling the eggs as soon as you see them!
