I have a betta fish named Lincoln that I got two weeks ago today. Last Sunday I moved him from a 1.3 gallon to a 5 gallon heated and filtered tank. I recently noticed his fin looking like it was ripped up, so I removed all his plastic plants and replaced them with silk plants and took out his decorations because I thought they were getting ripped from that. I am not sure if it is fin rot, the ends of his fins are not black or red. Lincoln does like to swim along the bottom of the tank mostly and his fins drag along the gravel sometimes. His water is fine I had it checked on Tuesday and I purchased an ammonia kit today and there is not any in his tank. I used the other strips as well and he does not have any Nitrates in his tank, the ph is fine, it is not alkaline.
