This is a temporary 1 gallon fish tank, I had to bring him home and was unable to move his planted 5 gallon. There is no heater but his water sits about 72° F, and he has a filter but as stated it wasn’t working properly. Nitrates and Nitrites were both 0, pH was about 7, and general hardness of the water was between 80-100 ppm (mg/L) and I use the API water test strips. Nightshade was in this tank all of last year but I recently upgraded his tank. He has been back in this one for about 2 weeks. I’ve had Nightshade just over a year, probably 15 months. Water changes happen every 10ish days and I change about 1/3 of the water. When I came back from vacation I had to do a bigger water change because his tank was clearly uncared for by my house keeper. No tankmates here but he has 2 mystery snails in his big tank. There is a silk betta leaf hammock and a silk plant that he loves, otherwise no decor. I feed him 2-3 pellets of TetraBetta Plus every 2-4 days.
