Thanks everyone! This forum is what made him so healthy :)
@Abby and hannah16- I agree! When I bought him, I had ZERO (let me repeat....ZERO) interest in owning a betta fish. I went into the store to buy my dog some Valentines day treats haha. I saw the condition the fish were in and was beyond appalled. Many of them were dead. So I walked out of there with a betta fish, got in my truck then thought to myself "crap, no what do I do?" So that is when I found this forum! I couldn't even tell what color he was through the murky water but when I got him into clean water I was blown away!
At this point I am just so happy to see him thriving! If I could I would change his color back- but I love that it means I am doing something right!
On a separate note, I believe the little guy may be constipated for the first time today :( Time for some fasting!
