Robby

He swims and eats fine, he has no tank mates, and water parameters are good. I feed him twice a day and he seems happy, I just worry about his fin

I bought this little guy yesterday, more like rescued from the local pet store, his fin has been like this since I saw him and hasn’t opened up, his other fins opened up some but this one hasn’t, he’s obviously very young, not even in his full colors, I don’t want him to die
