It's been a few weeks now and my Betta fish, Buddy, keeps tearing his fins on various decorations around the tank. Initially, there were 4 decorations in his tank, all fake plants from PetSmart's Top Fin brand. I'm down to one decoration in the tank now as he's torn his fins 3 separate times. I'm not considering adding live plants to my tank because I don't think there's enough light to sustain them in my room. So I'm asking, what decorations do you recommend for a 5 gallon tank and a Betta?
