what is the normal behaviour for these? i added 6 to my tank yesterday, and have been doing fine, but last say 3 hours they have been moving up and down the back of the glass, is this normal?
I have a gang of bronze corys in my tank and they're pretty active little guys, whizzing all over the place and digging around non-stop so I think it's pretty normal behaviour for them.
+1 perfectly normal behaviour, especially when they are new to the tank. they should settle down a bit but corys are notorious for their strange, yet highly entertaining behaviour!!! keep an eye on them (as i am sure you do with all your fish) but i really wouldn't be too concerned.

Mine are super active and swimming all over the place, so I think it's normal. Is the water stream of the filter in that area of the tank? I've found mine adore swiming against the current created by the filter.
