Sticky eggs are fish eggs.
Koi and goldfish are not live bearers.

Is hanging out in the waterfall new behavior?
Has the temperature risen lately?
Do you have any water tests?
Spawning can cause water quality problems.
And it sounds like you might be over stocked.
We figure 1,000 gallons for the first koi and 100 gallons for every koi added.
Comets should have 20 gallons each.
