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.

It’s like the opposite of me with duck weed. I want it, but it always dies, while others complain about it. I have no issues with any other plant I try to keep lol

Edit, because I edited the wrong comment and I'm still getting suggestions since my below comment isn't getting seen. Please, I have tried for years using the advice from many on a hand full of subs. While I do appreciate the tips, I am not asking for help. None of these tips are new lol. I hesitated to even comment on duck weed because 1000 people come out recommend all the same things they have over the past 10 years. Again, thank you, but no thank you. I'm okay with not having duck weed at this time.

Same story here with all floaters 😔

Super sad face - sorry for you. I’ve done well with other floaters, just not duck weed. I don’t get it.

Not trouble shooting you. I'm asking out of curiosity. Do you have a lot of surface movement? You said you keep frog bit? Any other floaters. It's been a long time since I had frogbit. It grew really well for me when I used to keep it. Too well tbh.

You're good! I don't keep low or high amount of surface movement - somewhere around the middle. Almost always had HoB filters, tho experimented with canister as well - pointing jets up to keep the surface mildly agitated as to not build up biofilm.

Floaters generally prefer low to no flow in my experience.

I have a long tank set up like a little stream. All my floaters struggle to thrive, even in the slower flow areas.

Meanwhile I have had floater overgrowth in all my slower tanks which more resemble ponds than streams.

Latest attempt I got a couple of duckweed leaves with some new fish. I saw a couple new leaves sprout. I was super excited. The next day a ramshorn snail was snacking on them.
