Yes! I would raise the temperature a little. I keep my tanks with my pairs in them between 86 and 88 degrees. Make sure to keep your oxygen levels up with those high temps though. My fish room is cool in the summer time. The advice about changing the water and adding cold water is excellent advice. It really does work well. You can also turn your heaters off for a few days or a week. Then turn them back on to the temps I stated earlier. I've had excellent results with this method as well. Also, the eggs will be fertilized through the egg crate if you continue to keep them separated. I do it from time to time when either the male or female is acting up. I hope this helps!
