My cousin gave me his 3.7 gallon tank (which included a heater, inbuilt filter and a thermostat) after his betta fish died a few days ago. He was upset and said that he was done with the hobby, because in his opinion he felt as though he did everything to ensure that his fish was healthy. I have fish also so I'm familiar with such requirements as cycling a tank, regular water changes and maintaining Ammonia: 0pmm, Nitrites: 0ppm and Nitrates to around 20ppm, etc. However, I haven't owned a Betta before. My question: is a 3.7 gallon tank enough for one betta and only one betta with nothing else besides perhaps a plant?
Personally, I feel that it is enough as I've seen my cousin's Betta actively swimming around and building a bubble nest. I don't know if it was because the fish was smaller but it seemed like there was plenty of room for it to swim as well. My cousin had kept him in that tank for a year and a half before the fish died.
However, I've seen plenty of people recommend that the minimum tank size for a betta is 5 gallons?
Can someone please provide me a concrete answer on this if possible as it seems to be varying opinions online.
Thank you.
