How do you breed Bronze Corydoras and raise the fry?

Answer 1

Bronze corys are perhaps the easiest catfish to breed. Here's a great article about them including some breeding info

Answer 2

It's true that it's easy to get bronze cories to spawn -- mine do it almost every week when I change their water. Eggs everywhere!

If there are other fish besides your cories in the tank, you should separate the eggs into a fry tank as soon as you can. My eggs usually don't last more than 4 hours or so -- the platies love them. ;)

Here's where it gets harder though.

To avoid fungusing and high death rate of the fry, move the eggs into a cycled 10 gallon tank (you can keep a filter sponge loose in the parent tank all the time and move it to the fry tank for instant cycles) and use a FILTER on it. Sponge filters are safest but a bit of nylon pantyhose rubber banded over the intake on a regular filter will keep the fry safe. Do partial water changes every other day at least. Fry are much more sensitive to poor water quality than their parents and you will be able to save many more of them with some extra effort. There is no need for gravel or sand in the fry tank and the bare bottom will be much easier to keep clean for them.

They also enjoy and grow best on specialized foods. Here is a thread discussing the whole process:

Answer 3

One of my corys just laid eggs a few weeks ago. I read somewhere to add slightly cooler water(not to dramaticly cool though) that triggers them to lay eggs. I scraped all the eggs I saw on the glass and plants, and put them in a breeder net. There were a few fry that hatched, but most of the eggs turned fungusy. The next day, only 1 fry was left, didn't have much hope for it, was swimming around in circles. Still alive and growing like a weed in the breeder net though. I drop in some shrimp pellets-because they dissolve fairly well, and he can pick at them. I also crush up some flake food and spirulina flakes in my hand, almost to a powder, then put that in for him to eat. Loves the spirulina flakes mostly. Most fish you can trigger spawning by a slight raising or lowering of the temperature or trying different foods like brine shrimp.

before everything congratulations your corys might desire to be extra advantageous than happy and cozy in there domicile to reproduce : ) the two the eggs might desire to be removed from all different fish inclusive of dad and mom or dad and mom and fish removed from the eggs. it truly is simply by fact there's a threat of alternative fish ingesting the eggs, even the dad and mom might desire to snack on them. The eggs might desire to be located mutually on the tank wall or yet another vertical floor. you will discover that the eggs are particularly sticky, and can truly truly be rolled off the tank wall and onto your finger, in case you desire to flow them. it truly is terrific to no longer disclose the eggs to air, and do make valuable to be careful whilst shifting them so as that they do no longer look to be broken or perhaps destroyed. to assist avert fungal growth (which might bring about the eggs no longer hatching) the eggs might desire to be located in some form of water pass. an person-friendly way is to easily place an airstone below the eggs. Fertile eggs will look truly beige in colour, and could strengthen a darker spot in the middle as hatching will become close to. Infertile eggs will look straight forward and white/translucent. The eggs might desire to take approximately 3+ days to hatch, and whilst they hatch they are going to be easily tiny. desire this enables
