I've had a school of 10 corydora juliis for months now and there's still no sign of them pairing up. They're all over an inch and a half, so they're not too young. Would a waterchange help? I'd appreciate any advice. Thanks.
Why won't my cories pair up?

They probably need a trigger. A trigger is an environmental factor that get a fish "in the mood" sometimes it is the addition of live food, a water change, cooler or warmer water etc. Look up some info on google on how to spawn your species.
There are several types of corys and some have different requirements than others, many mob breed instead of pair. A trigger is usually required. here is a link that will describe one type of trigger. http://mike-edwardes.members.beeb.net/stumped.html
I used to breed dwarf pandas in the summer by using a hard plastic kiddie pool on the patio, it contained several box filters, a couple heaters clipped to panes of glass, and bunchs of elodea, the bottom was covered in marbles and several several flat peices of flat slate and flower pot shards. Iwould feed for saeveral days using minced earthworm and tubifex as well as brine shrimp. I had the heaters set at 76 F but during the daythe temp reached mid 80s. I let about 10-15% of the water evaporate then did a 30% water change, refilling it to the original level with water a few degrees cooler than the pool water. then shaded the area with a garden screen, they started breeding that day, eggs hatch in about three days. They bred on their own a couple days ahead of schedule once after a heavy rain. I would start with a couple dozen cats. After a couple weeks I started giving them away to everyone I knew.
