I am new here, but I was wanting some information and thoughts about what I should do for my Betta, Isaac. I've had him for about 7 months. I am unsure if the tank I have for him is a 1.5 gallon or 2 gallon tank. I do not have a heater for him, but I do have a filter. I have an aquarium light I turn on during the day for him. I also try to give him areas to hide in the tank. I also have a live plant in the tank.
Yesterday I cleaned out his tank and waited until today to put him in to his clean tank and as I was putting him in the tank, somehow he ended on the floor instead of the tank. I picked him up as fast as I could and put him back in the water, but now he is swimming near the top of the water and his right eye is pretty swollen. His color seems to be a little more dim than he normally is.
Normally I have a fake plant in the tank that he likes to stay in, but with his eye swollen he seems to be getting caught in the fake plant so I took it out fearing he may hurt himself in it. I am also unsure if I should keep the aquarium light on for him or turn it off.
I have included 2 pictures of Isaac. They are not a good quality because they were taken with my web cam, but hopefully you can see how swollen his eye is in them.
I appreciate any input on what I should do for him. One main issue I have is how much I can afford right now. After reading through the forum I have decided to get a heater for him but I can't afford to until next week.
