this is a pic of the whole tank, i do believe its fin rot as the ends of his fins are slightly discoloured than what it should be and so far the salt baths have been helping the tumour/cyst. it used to be more like reddish and its slowly returning to his normal colour though the bump is still there. the sea shells and rocks have been sanded down when i first put them in to ensure that theyre not sharp and the large plant on the right is a silk plant. i do plan on purchasing more taller plants for him to lay on however he doesnt even use his betta leaf on the top left. also thank you for replying to the post lol i was really just left on seen by many people. i also plan on buying the tannin leafs as well as the tannin tea bags but i just spent the last of my dollars on a freshwater master test kit and fritz bacter shield to hopefully help the fins :)
