I'm curious how many Astronotus ocellatus you two have had collectively since I've never experienced a "lazy" one in nearly 3 decades, especially since at that size is when they're sexually matured.
Ok well they dont really get "lazy" per-say but they dont move around as much. I had one in a 55. Had one in a 75. And had one in my 150 abd they all became less active around 8-9". Although i did get them all from petco. But one oscar in a 55 is ok as long as the person has good WC schedule and filtration is good.
