Ok so I have decided to do a small write up on how my Cory’s breed:

Tank:

Standard 3ft tank, full of plants.

Substrate:

Got it with the tank, called “Pea” Gravel.

Temperature:

I have my tank on 26C during the day, and during night it falls to 25C-25.5C.

To start off, I have three Albino Cory’s in my tank, Two females and one male. I feed my Cory’s Nutrifin (spelling) for bottom feeders, I feed them this twice a day. Once a week they get some Bloodworms as a booster.
I do my Water Changes on a Sunday or a Monday, and this is 30%-40% and a small one in the middle of the week 10%-20%.
I have never forced the Cory’s to spawn. They usually spawn over the weekend, except for the last one, that was on a Thursday. My lights are on a timer. Starting @ 06:00-12:00 the off until 15:00 and then on until 18:00. For some reason they always spawn as the lights come on, and this gives me enough time to collect the eggs, no matter what day of the week it is! They almost never spawn on the glass of my tank, they love the Giant Hygro and the HOB filter for some reason! Once I have collected all the eggs that I could see, I place them in a clean Guppy breeder, and add an air stone. I do a 50-70% WC in the morning and again in the evening just before lights out. By the second day you will notice that the fertilized eggs have developed a small blackish dot in the middle. I monitor the rest of the eggs for any late “bloomers” as well as to remove any of the eggs that start to grow fungus! 5 hours before they hatch I start to notice them move in the eggs, and then I know the time is near. Once they hatch, don’t move the breeder, as they will be sucked out. i then take a large straw or a filter pipe, and suck them up one by one, and place them in a container. 2-3 days after hatching you will notice that the Yolk sacks have been used up, and it’s time to feed them. I have tried the whole BBS, but that’s a bit pricey, so I have found the following that also works well, buy a bag of Brine Shrimps, and chop them up and give them to the Fry. All of them chow this like mad.

I do this twice a day, and still cleaning the containers twice a day. By day 3-4 after they have hatched, I start to feed them some of the Prof’s food, as it contains some shrimps. At first it does not look they eat it, just leave it for a while. I then mix the two up, giving the shrimps in the morning and the Granules at night. In week two, they are a lot bigger, and they are only eating the granules, it’s at this point when I start to feed them some of the Nutrifin Pellets, all I do is add one to the container, and once its soft, I break it up for them.

Cleaning the containers:

During the whole process, I will remove the Fry and place them in a small holding container, and clean the original one ( I do this in the tank, just use a small piece of sponge and clean it) and place the Fry back in the container. I do this every day. This is my holding container:

This is what works for me, i cannot confirm that this will work for the rest. I will be feeding my new Fry some Microworms and see how that works out.

Breeding behaviour:

I have been “documenting” this for a while now, and would like to mention this. This is only for the Albino’s: I can tell that my females are almost ready to spawn, as the normal colour is white”ish”, but 2-3 days before they spawn, they start to get Pink, yip Pink. And they start to swell up, then you know that they are ready, some say that you can then do a small WC to trigger the Spawn, I have not tried this, so I’m unable to confirm. The morning of the spawn, my female will start her “Shark Swim”, this is what I call it, it’s when she starts to swim at the top of the tank, her dorsal fin will break the surface, looking like Jaws hehe. She will swim the entire length of the tank for a few minutes, the male will pick this up, and will start his dance? He starts to shakes his body against some of the plants in the tank. I really don’t know what he is doing, after a few dances, he will start to follow the females, swimming all around her, and tapping her on the head, and once she’s ready, she will allow him in front of her, and they will start the T- position showed below.


By doing this, she will swallow the males sperm, and fertilize the eggs internally. She will the place the eggs in her pelvic fins, swim around and select a spawn site, this will happen a few times, as I have counted up to 8 times. if the conditions are great, spawning can take place every two weeks, my last spawn happened 10 days apart.

Well thats my story

A very informative write up Vez.
