Hello,

So this morning I saw my school of bronze corydas acting like they are breeding and now I saw quiet a few eggs on glass and plants.

I've never successfully bred cory catfish before so Im not sure if I should intervene or not to increase the egg surviability

I googled around and some says it's not necessary as scrapping off the eggs can damage it while others say I should move the eggs to a seperate tank to rear the fries.

The tank is 1.7m long and heavily planted with tank mates:
- 2 blue phantom plecos (Young, less than 10cm long)
- 12 Bronze cories
- 12 Sterbai cories
- Bunch of pest snails (Malaysian trumpet mostly)

The majority of the eggs are also near the water out flow of the filter so I'm also concerned that maybe when the eggs hatched, the wrigglers or fries will be sucked into the filter canister.

So should I leave the eggs like that or should I do something?

They will almost certainly be eaten if they stay in the tank so I would remove them. I would put them in a plastic tub filled with water from the tank, with an airstone, and float it in the tank.

Thanks for reply

I will take the eggs out if they are still alive tomorrow

Gotta figure out how to do it though, Im really afraid I will break the eggs

I usually just gently roll them off the glass with a fingertip.

Will try that tonight after work.

How long you think it will be okay for the babies to be back into the main tank?

I see a lot of people are raising them in a bucket but since I have a spare tank (60l) + filter. Maybe I can just use that instead of a bucket so I can easier observe the fish?

Set up a breeder box in the tank.... but I ended up destroying/dropping like 40% of the eggs while trying to collect them.

It's so much harder than it looks

They are slow growers so will be a good couple of months before they can go in the main tank.
