Breeding Corydoras

Breeding Corydoras


Hello
I was wondering if anyone had any success breeding corydoras? I have 12 in my 75 gallon. They are really neat. They are definately one of my top favorite inhabitants. Eight of them were given to me by a person who could no longer house them and they have since been in my aquarium (approx 2-3 months). Their prior owner said they did spawn all the time but I think with the big change in environment they do not want too. So basically my question is if there are any members on the forum that have success in getting their corys to spawn could you give me some pointers.

Thanks in advance.

 

what are you water parameters, temp, how often do you do water changes etc.

 

The parameters last time I tested were...
Ammonia/Nitrites 0
Nitrates between 5 ppm
pH ranges 6.8-7
Temp. ranges kept around 75.

Water changes at least once if not twice a week.

75 gallon
Fish inhabitants...
2 juvie gold severums
1 jelly been parrot (very small)
12 cory cats
1 rainbow shark
2 baby angels (being moved shortly) just purchase a second tank.

 

try doing a water change and raising the temp slowly to around 80 or 82. This might cause them to spawn.

 

Nice catch anthony I completely overlooked that part. That would be my guess as to whats happening since corys dont watch their eggs and lay them all over the tank. All the shark has to do is follow them with an empty stomach.

 

See I have read that you would bring the temp down. Maybe that is what I am doing wrong. I will try bringing it up. When I do a water change I put slightly cooler water in and they seem to get really really excited and interact alot with eachother. They swin to the surface like a dart and then some follow the side of the tank up and down, up and down for sometimes for like 1/2 hour. I have not seen the famous T thing that the websites have said they do before they spawn but that does not mean anything. Maybe it is sharky. I really like the shark he is find with the corys but does not like the sevs or jelly bean to get into his space. It is really funny. I am planning on starting another tank with just a couple angels. Maybe I will put a handful of the corys in with them and see what happens.
Thanks everyone.
Could anyone recommend a good conditioning food for the corys?

 

I should have specified that ever since reading they spawn with cooler water which would indicate a rain storm or shower I have been doing water changes with alittle cooler water. Before that I always refilled with water that was about the same temp.

I have been feeding them a mix of freezed dried blood worm and shrimp brine pellets. Also an occasional frozen shrimp.

 

You might need to keep the tank and 80 for a while (two weeks or so) and then lower the temp to spark their urge to make or trick them into thinking there was a rainfall.

 

The eight I took in are pretty large. I wanna say about 2". I would consider them full grow. I do have 4 others that are small about an 1" they are young. I have had the eight for a couple months, and the 4 little ones for 5 months.

Cooler water changes are the correct thing to do. 50% WC's everyday with cooler water and feed them frozen bloodworms. You will have eggs in a week or two. Mine spawn all the time, C. Aeneus, you will have to remove the eggs if you want them to hatch
