So my sister had a betta, and since she never asked me for help with him so I assumed he was fine. He… was not. Hardly 2 inches of water, cloudy, and sad. Shes past the age of needlessly killing pets, and i have taken custody of the fish until she is deemed capable. I dont have money for another tank for him, but the 2.5 gallon will hopefully be good until i can buy a bigger one. Im getting the filter off Amazon in about a week to hook up to my air pump, and will do as many water changes as possible to try and fix the cloudy water. Hes a charming little character named obby, he flared at my female before i put a folder between their tanks. My female is three years old at this point and hardly interested in such a small male, but he will hopefully get bigger. I added some of my real plants and took out the fake ones that crowded her tank, so now there is plenty of swimming room. Are there any recommendations on how to fix the water until i can get the filter? I want to make sure he is happy as a clam while we wait. The first two pictures are from when i first saw him, and the second is after giving him some water and a small water change. Yes, i posted this to Reddit so they are the same pictures lol
