Last time a female laid, it was in a 10 foot holding tank. Turned it into a giant snow globe. Millions of tiny eggs. We netted some of it out. What got sucked in clogged the filter repeatedly all day. Lots of backwashing and netting did the trick, but there were some there until we pulled the fish out and dumped the whole system. If the pacu spawn on display, I'm hoping the silver dollars and cichlids will eat them all. It's going to be a nightmare to clean if they don't.
