I changed jobs a couple years ago, and made some lifestyle adjustments. I used to run tons of tanks, and in the process figured out which ones were a lot of work, and which ones weren't. I initially "downsized" to two, making room for music on one side where a rack and stand alone once lived, replacing a couple racks on the other side with a 125, big corner tank and a full length bookshelf. I couldn't resist bringing my most unique tank back online as a standalone, and after changing jobs (again) I brought my work nano tank home to live on my writing desk.
I have figured out the plant mass and types required to make all 4 (even the Tanganyika tank) very low maintenance and don't feel like I need to focus hours per day on them to enjoy the beauty and tranquility they bring to my home, still enjoying the emersive experiences I have when I bring a comfy lounge chair along side them to unwind. I'm only
changing water and doing planting work about 4 hours every two to three weeks, and now feed about every 2 days. Every few months I give away a couple buckets of plants and as many fish as I can net or trap without it turning into an excursion and it really works for me.
I selected 4th as I definitely have higher maintenance hobbies and responsibilities so the tanks can take a backseat, but they are still very much a big part of my lifestyle and mental health. I can't write a note on a sheet without watching my shrimp or shellies going about their busy day, and after a period of mental stress, getting lost in the details of the underwater world in the big tank does wonders for me. Without my quick water change system and water chemistry, planting and general husbandry knowledge, I would sadly have to let them go.
