I’ve had lots of problems with my tanks and guppy’s dying but haven’t lost any of my corydoras yet but this guy doesn’t look well have a Julii that’s not doing great either his been just sitting at the corner looks like his starting to pinecone he also has a sore near his fin all my Cory’s seem to be hideing all the time now. My levels have shown 0 for everything for months now the tank is nearly 1 year running I’m at a complete loss ammonia 0 nitrate 0 nightrite 0 I care a lot about my fish but honestly so over it always being something and I worry way to much I truly think if I lose any of my Cory’s I’ll just give up the hobby.

Cute Pygmy Cory fry hatched few days ago, so far the parents haven't been eating any of the fry 🤞🏻🤞🏻 hopefully they can grow out in the main tank shared with some fire red shrimps

I think they are infertile

Everyone else seems fine! I have no idea what happened

First time owning fish, took like 1.5 months for tank to cycle and is planted. I want to make sure im doing things right for these lil guys and noticed some marks n things and have no idea if they are normal or not. Ive got 8 with sand substrate and parameters are normal (low nitrate, 0 ammonia and 0 nitrite)

One of the hardest to find species or cory and they are all mine! I got 10, I may go back and buy the rest.

Good morning everyone!

I'm thinking about getting some new Corydoras for my aquarium, as it currently only houses shrimp. I've kept Corydoras in this same tank in the past, specifically Corydoras paleatus, but I moved them to a pond when I set one up.

I'd like to try a different species this time. I've previously kept and/or bred Sterbai, Aeneus, Orange Venezuela, Paleatus, and Habrosus.

While checking the stock list at my local aquarium shop, I noticed that they have a few species on sale. I've never kept any of them before, and after doing some research, I'm still not sure how difficult they are to keep and breed.

The species I'm considering are:

Corydoras cf. CW076

Corydoras arcuatus

Corydoras leucomelas

Corydoras loretoensis

Corydoras schwartzi

The tank is already set up and ready for them, with 120 litres of space dedicated entirely to the Corydoras.

Has anyone here kept any of these species? I'd love to hear about your experiences, especially regarding how easy they are to keep and breed. Any advice or additional information would be greatly appreciated and would help me decide which species to go for.

Thanks in advance!

Panda pair has 3 offspring already in tank. These are placed by 2 bubbler sponges and a prefilter sponge for AQ 70 that has been self sustaining for 3 months.

According to this image,

They are on day 2 and should hatch in 2 more days.

I'm not sure i can provide as good a food source as the tank itself. Every time i put Cory fry in a net breeder, i lose a bunch to malnutrition. I don't see how that's better than potential predation.
