I worked in private Lfs for 3 many yrs ago, at that time we had large tanks & large cichlids at our house(Red Devils, green terrors, oscars, convicts, etc.) now I got out of the hobby & restarted again about 8 yrs ago with Bettas. I picked Bettas because I didn’t want all the maintenance that comes with 55,75, 150 tanks ☹. So I’ve now went from betta bowl to 5 to 10 to 20 to 46 gallon. Long story short, I’ve keep my Bettas & also had gotten puffers, angels & discus, etc. since then. I have 46 gallon with female betta(cupcake), angels & discus. I love exotic Bettas, she was yellow- turned opaque/red on me. Now cupcake was ok with a few angels & more fish I added, the more cupcake hides. Moved them all to 46, added more fish- angel & discus tank & cupcakes like heck no. She mainly hides in bushy plant I have in their. They’ve never tried to eat her, but the angels were dime size when they were first introduced together in 20g. Now the angels & discus are huge compared to her and she mainly hides. I really don’t want to set up another tank just for a betta.
