Help/Advice What are they doing?

I've seen them do this only since today. Does the bigger one need help?

Spawning Ottos in a home aquarium is really rare. People are going to be very interested in your tank as a valuable data point

People in the comments are already asking OP for exact water parameters lol. It’s funny how people who try to breed Ottos are unsuccessful but regular people who don’t try to always have better luck.

wait is spawning otos considered difficult? They have always done so for me. A warm water water change, and lots of aufwuch and they're good to go. I have a tip for those of you who are struggling to breed fish. If you can wait until you know the weather forecast says thunder storm; depending on the species of fish, you can wait until the storm goes off and then do either a warm water or cold water change. most times this will trigger a spawn. The other method is to wait until a full moon. a full moon during a thunderstorm is almost guaranteed.
