I have a betta fish in a 10 gallon tank with driftwood and Anubis plants. I had him in with ember tetras for about a head before I saw them snipping at his fins! He’s a half moon betta and his fins are destroyed! I re homes the tetras about year ago and his fins never fully healed, but he seemed to be doing fine. He’s active and healthy. I just now noticed his top fin is short and it has white fuzz on it. Is this fin rot? I want to add to sand fins f almond leaves but I have a mystery snail, and notate snails, will this make the ph to low for them? What should is do? I don’t feel confident with any harsh medications.
