0.5 on a pH scale is not an overly large pH change - especially if it is from or towards 7 (remembering that pH is a logarithmic scale). The vast majority of river dwelling fish will take that without a problem.

But if you do have vastly differing situations like yours then yes, but I did say make sure pH are close and throw them in, and still stand by it.

In the 20g the P.H. is 7.6 and I think the tap is the same.

If that's the case, then as andywg said, you can pretty much just fill the new tank and move the fish over. I would go through an acclimation period though just as when you bought them.

Well I wasn't going to do that I was going to float them in the bag for 20 minutes and then I'm going to open the bag and add some water wait 5 minutes then add some more then wait 5 minutes then I'll do it again before I add them. Is that a good idea?

If thats what you do when you bring your fishies home from the store then that should suffice, but the idea of adding old water from your other tank isnt because they need it becuase they dont, but it does help to make it a bit less stresful. remember fish VERY rarely actually undergo 100% (or near on) in the wild

Remember these are tropical freshwater fish, not marine. Their natural habit is subject to changes due to rainfall and seasonal variations in landscape.

natural variations are different from 100% water changes, how often do you 100% water change your fish?

I myself would add all the water to the tank before throwing the fish in so they do not have the stress of the move followed immediately by the stress of the added water.

Shouldn't actually be much different from a water change, how stressful do you make yours?
