Torrey, I so appreciate your responses. I have been beating myself up because I love the little guy and want to do well by him.
My sponge filter should be delivered tomorrow. I have not tried colu's medicated food but I will quickly buy the ingredients if you think it will help. When looking at your and Colu's previous posts, I've gathered that I will need kanaplex, focus, and better betta food.
Would you recommend using xtreme aquatic nano foods 2207 or hikari bio-pure freeze dried daphnia (both from amazon) to mix with the kanaplex and focus? Would you then feed the medicated food twice a day like normal?
I have the tank at 80 degrees so I will turn it up to 82 degrees and I will start doing two water changes daily instead of every other day. Further, I will add more AIL leaves because it seems like my water is not as dark as what you're describing.
Finally, regarding what you shared about removing anything rough from the tank, I have a structure in the tank that, although it doesn't have any sharp edges, it is a rough structure. Would you recommend removing this? My betta really likes to hide in it so I don't want to stress him out by removing it but I also don't want him to tear his fins worse. You can reference earlier pictures to see the structure.
Thanks again!
