Who here has had clown's spawn?

[DJ88]

My female perc is loookin mighty fat and is not as active. I know it isn't from over feeding as they get fed once or twice a week(mabye). All the other fish are chubby from eating waht they find in the tank so no worries there.

Any behavioral changes I should keep an eye out for as a good indicator for a spawn a comin?

TIA
