Breeding set up

eupterus · Post by **eupterus** » 09 Oct 2005, 18:06

I am wanting to start breeding corydoras and am yet undecided on the set up to begin with. Initially i have room for 2 36 X 15 X 18 Tanks that I am planning on dividing. The question is conditions, filtration and how to divide the tanks. I am wanting to start on the more common species ( paleatus, aeneaus julii etc ) I have large tanks for rearing fry. Any help and advise would be appreciated

Thanks

I have seperate tanks for breeding Corydoras, but I guess it's close to the same as dividing larger tanks. I use HMF-filters i each tank. You could also use a central filter, but i think a large airpump with HMF-filters are perfect. With the central filter you could spread diseases between the tanks, wich you could avoid better with seperate filters.

I use sand as substrate, but you could use bare bottom as well. I just think the sand makes the fish more comfortable and not so easy to spook. As far as plants go, java moss and javafern would be just fine, maybe along with cabomba or elodea. Some pieces of wood and maybe small rocks would be good for cover.

I would divide the tanks with either glass or plastic of some sort.

...if you don't have Ian's book on bredding Corydoras, it could be a very great help too...

Hope you can use this...

What water parameters do you use, our tap water is 8.0 and hard. Also I was planning to house the corys in groups of 6 two male and four female. As for the tank size, I was thinking of dividing the tank into either 2 18x15 x12 or three 12x12x12 sections, leaving the water flow through each will mean in reality the water they are in is still 36x15x12. Any thoughts

I use rainwater...never had any problems with using this.
Don't you mean the other way around regarding sexes?...4 male to 2 female? Usually more males than females are recommended, and I usually group my fish this way too (more males than females).

I think the dividing of the tank into 2 or 3 sectuions depends on the species you want to keep. I'd go for 2 sections with theaeneus and paleatus, as they grow rather large.
