Hi all. I've had my betta for roughly 3 months and they've been doing great so far. However, I noticed that the pelvic fins appear torn and there is a thin white string hanging off of each fin. There is also white tips on the tail. Mind you, my betta's pelvic fins have always been slightly torn (since I bought it) and I believe the tips on the tail were white too...I've just noticed it more as of late. In any case, I've read in depth about fin rot and I think my betta may have it. Not sure if I'm overthinking but thought I would get advice first before I purchase medication or treat it unnecessarily. I spoke with a PetSmart rep (on the phone) and they advised "BettaFix" but because I can't physically go in to the Pet Store and show them pics of my fish I want more opinions. Also, I've read on this forum that Aqueon Betta Food isn't the best brand. Can you also recommend better food? All help is greatly appreciated
