Switching Tanks?

[Khanna]

I'm thinking about moving my cories over to my 10 gallon, and then getting a betta fish. My question is, what's the procedure on moving those fish? Should I get a bag like I brought them in from petsmart? I mean the temperature would be the same, so they wouldn't have to get used to the temperature..  I'd move all three of them. So what do I do?

Don't put your fish in a bag. It's stressful.
I normally just net and drop the fish between tanks because my water parameters are the same except for slight temperature difference but they can handle 1-2 degrees just fine, especially corys.  I use a net, but I put a plastic cup under it once I catch the fish so the fish doesn't spend any lenght of time out of the water. This is to minimise stress.
If you have any tests for Ph, Gh, Kh or a TDS meter, test these. In tanks that have received water changes from the same tap water regularly, there isn't any major difference in parameters.

How close together are the tanks and are there heaters in it?  Do you suspect any differences in pH, hardness, salinity, etc?
 
You could do a drip acclimation to the other tank.  That is the safest, in terms easing the change in water conditions.  Drip acclimations tend to be stressful though, as it requires them to be in a container for 30 minutes to an hour.


I agree with sanzy.  Bags are bad.

Just scoop them  up with you net and chuck (not literally) them in. Unless you are talking about a distance transfer.
 
Why not use some of your old aquarium water in the "new" tank as well? That way the water parameter should be (almost) exactly the same.

I use the net&drop method, but almost all levels in all of my tanks are similar.

I have a question:
What size was their tank beforehand?
 
Assuming all your tanks are close in water stats, you should be just fine with just netting the fish and releasing them in the other. That's how I do all my fish if I'm switching things around. This, of course, would be a bad idea for fish recently purchased/arrived from a store.

It'd be a 20 gal to a 10 gal. The water parameters and heat would be the same, and the tank is about twenty feet away. They've been in the 20 gal for about 2 months. So I can just net them, fly over to the other tank, and release?

 

[snazy]

I'd say you should be fine doing this. If water stats are similar, that's the least stressful way and probably best in this scenario.

Relatively few Corydora species are suitable for a 10g long term, which species do you have?
 
Having just 3 is far from ideal, the only species exception that immediately springs to mind are Schleromystax barbatus from the corydora-like family. Maybe you should think about rehoming them to someone who can keep a 10+ group in a suitably sized tank, which typically means something with at least a 90x30cm footprint, with the exception of Corydoras hastatus; habrosus; pygmeus; panda.

I'll take the corys but, they do need large groups.
