Cory's growth rate

[ellner357]

I'm just curious, I have 6 baby cories and 1 adult (no relation) I'm curious how quickly do these little guys grow? What can I do to help them grow besides feed them well and keep the water clean?

Should get to 1 inch at about 5 months i think.. somebody correct me if im wrong.

pre soak some powdered flake and feed that alternated with newly hatched brine shrimp for food.

Growth rates in corys can be improved by adding some calcium to the water they draw alot of this from the water column to form their amour plates along their body. U can add about a 1cm square cube of plaster of paris to your fry tanks and let it dissovle before u add any more you can also add a small amount of epsom salts (magnesium sulphate) to this plaster mix if you do this next time round i think you will also have a better survival rate as well.

They're little, but not fry little. more like half inch little. But They should grow quickly enough lol.

It depends on the species. This article (http://www.scotcat.com/articles/article46.htm) is fantastic, showing you the growth rates of seven Corydoras species and it includes illustrations. There is no better authority on Cory's than Ian Fuller, who wrote the article. He has published a couple of books about them that no Cory breeder should be without. You may find something specific about the species you keep here (http://www.scotcat.com/articles/articles_breeding.htm).

My C. aeneus recently spawned, and in about one month the fry are already half an inch or more. Corydoras tend to grow quite fast at first, but when they hit about 1-1.5in. they slow down quite a bit IME, and it can take them years to grow to their full size.

Try feeding them tubifex worms. I've noticed my Cories love them and it does increase their growth rate IME.
