These are just general fish health/appearance questions. I wasn't sure where to really put this, or what to call since I have questions on two different fish.
First, this is Sawyer. I'm treating him for internal parasites in a 1 gallon tank. Only silk plants in it, and I've noticed that his bottom fins are kinda shredded/holey on the ends. I just wanted to make sure that it wasn't from ammonia or something.
Sorry it is big, but it's hard to see the fins in a smaller sized pic.
And this is my new one. I was looking at pics I took of him when I noticed that one made it look like he had some sort of growth behind his pectoral fin.
But when I went to look at him, I couldn't really see anything unusual. He's my first multicolored one, so I wasn't sure if it's just the way his body colors are. Does it look like anything? Here's a video.
