Who's Eggs Are These

[KirkyArcher]

Appeared overnight several deposits of eggs, lots of similar sized clutches on the front glass and also on the underside of my Algae scrapper

Tank contents, Apistogramma agassizi, Corrydoras sp. (Black Venezuela), Corydoras paleatus (salt and pepper), Rummynose Tetra, & Silvertip Tetra
 
any hints and tips as to best ensure survival?

I would rule out the apistogramma as they are more of a cave spawner. I would also rule out both tetras as they usually lay there eggs in the substrate. So that leaves the corydoras and I think they look like Cory eggs. I don't know what ones they are but if I had to guess I would say salt and pepper from Tom

 

[KirkyArcher]

Yes, I now believe them to be from the Corys, Apistogramma eggs tend to be a deep red colour. Just "harvested" them the best I could and put them in the hatchery box, lets see how it goes

Corrydoras sp. (Black Venezuela), Corydoras paleatus (salt and pepper)
 
Best bet...
 
 
FYI, Corydoras paleatus are 'Peppered corys'. http/www.planetcatfish.com/common/species.php?species_id=271
 
Common name 'salt and pepper cories' is for Corydoras habrosus. http/www.planetcatfish.com/common/species.php?species_id=482

Oops! They are definitely Paleatus (Peppered cory) in the tank in question

I have the Salt & pepper (habrosus) in the 200 litre with the agassizii

................Anyway, despite my best efforts to ensure water flow and oxygen levels were adequate enough, the eggs in the hatchery tank are now fungus covered, and the remaining eggs I left on the glass behind the Co2 diffuser, I've just watched my male apistogramma agassizii devour them

Let me offer a different way of hatching the eggs for the next time, if you are interested in raising the fry...

3. How do I hatch them?
There are several ways to consolidate a spawning, but it is spawnings in community aquaria that initiate the most requests for help. The easiest only requires a small shallow, 1.5 litre plastic container, something like a sandwich box is ideal, and an air stone. The container is three quarters filled with water and floated on the surface of the main aquarium, the eggs can be removed from the aquarium sides with the aid of a clean razor blade and put into the container, where eggs have been placed on plant leaves the leaves can be cut from the plant and placed into the container. The air stone ensures that the water is both fully oxygenated continually moving, which helps to prevent damaging particles from settling on and contaminating the eggs. At this stage one or two drops of a propriety anti fungal preparation added to the water in the container can also help to prevent fungal spores from attacking the eggs. If medication were used then I would recommend that 50% water changes be made to the container each day for the first three days. Use replacement water from the main aquarium, this will dilute the medication in the container, so that by the time the fry hatch the water will be the same as the main aquarium

 
FYI... "Coryman" is actually Ian Fuller, one of the world's leading ichthyologists in the world - and one of, if not the leading one for corydoras research.

Cool thanks very much
