Betta fin tear? and weird growth on driftwood
Hello, my betta fish Malfice is new and I got him about three weeks ago, he lives in a 3.5 gal tank with a heater, filtration, natural aquarium soil and plants as well as a piece of driftwood. This morning I noticed he had a tear in his tail fin seemingly he got it overnight? And there is a weird fungal-like growth covering the driftwood, could that be a reason for concern? How do I treat the tear?
