I found it very helpful with my breeding. If the female is not showing all of the signs i'd say she's not ready to breed just yet. maybe return her to her container and leave them another 24 hours? But yeah, its normal for them to chase each other for a little while before they spawn!!
It may be worth trying again in 24 hours when the male has had time to build himself a nice nest! You have to expect some chasing and fin nipping It took my two about 2 hours of dancing and wiggling at each other before they decided to get on with it!
