i just got a new 75 gallon tank..
thinking of using this as breeding tank for my cories
will bigger tank be better for breeding?

Not necessarily.

A bigger tank is better for holding higher number of fishes, or bigger fishes.

For breeding purposes, you need a tank big enough to hold your breeding colony with ease.

For cories, a good size breeding colony would be about 5-7 cories, at about 2-3 inches each. That means about 10-21 inches of fish. One inch of fish per 3 gallon, which is PLENTY roomy, and that's on 7 of the biggest cories you can find.

But there's nothing WRONG with this, just that you're spending a lot of money on a big tank that is going to be mostly empty. You could probably spend the same money and get three 25g tanks that would be more than suitable for 5-7 cories, if they are adequately set up.
Then you can breed three different varieties at the same time too.

But that's just my ideas...

A ten gallon aquarium is of sufficient size to breed most corys. Larger tanks are necessary for barbatus and similar sized fish. I have bred most of my Corys in tanks of this size. I know Ian uses similar sized tanks as well. Again, depending on species five fish are enough of a group for a ten. What species of Corys are you interested in breeding?

thanks
i'm planning to breed my trilineatus and sterbais..
also hoping that i can breed my arcuatus. but heard that they are really hard to breed.
btw would it be better to have some driftwoods in thetank?
or will it be ok just to have a filter and some spawning mops?
planning to use my 35 gallon tank for breeding instead
and use the 75 gallon for my argentea:)
