I’ve noticed my betta has fin rot so went to my local fish shop , they gave me protozin and said to treat day 1,2,3 and 6. I’ve also been feeding frozen food as he is looking very skinny. What should I do after this?
I’m not sure what type of wood it is, it appeared a couple weeks ago and I took it out and boiled the wood for a couple hours. I haven’t put the fish in yet as it’s in a different tank.
