I have a freshwater tank, 55 gallons with tiger barbs, tinfoil barbs, rainbow shark, bala shark, Pleco, and a pictus catfish.

I bought some java moss and Anabias. The planting guide that the seller sent me says to add 1 teaspoon of epson salt per gallon of water once a month to keep the plants green. Is this just for a planted tank with no fish???

I also have a silver tipped shark (catfish) or a Columbian catfish, After I added him to the tank I read they like brackish tanks.

Can I add aquarium salt to the tank to satisfy the silver tipped sharks, and hopefully it will not harm my other fish, also Will it harm me plants??

Salt isn't needed for plants. Brackish tanks are best made using ocean salt, all your other fish won't tolerate a brackish tank. And yes the salt will harm most plants.
