fin problem

Hey I’m curious about my niger trigger fin. Iv had him for 3 months and I noticed his bottom fin was damaged. He has been eating regularly and it seems to not bother him. I’m not sure if it’s fin rot or a mechanical damage. Any thoughts? Thank you!

This morning I noticed that my hippo is favoring one fin. I can’t tell if he is injured or has the start of a fin disease. video is long - around the 2 min mark is a good shot. I was videoing the Anthias as well. He was introduced to the tank a month ago. He came larger that I thought he would...

Good afternoon, this is my new BIOTA yellow tang. Small little guy. Purchased this from a local LFS yesterday. In the shop I noticed all the little new boots yellow tangs had fins that looked damaged. Was told my owner that they usually come with some fins nipped from shipping from all the fish...

Hi All, My bristle tooth tang has recently completed 8 weeks of quarantine. During the last 2 weeks of quarantine I adopted a hybrid approach that employed several different techniques I've read about online. This included a formalin dip of 45mins, tank transfers every 36 hours (with new...

Hi guys! So picked up this pair on Saturday. Acclimated and popped them into my 180L tank, where they both hid in the rock work. Noticed this morning that one seems to have rather damaged fins, not sure if fin rot or is just from stress or perhaps bullying at the LFS? Is not eating but then has...

One day he was fine and last night he looked like this . He’s not eating. Was he attacked by a hermit crab? Is it a parasite or bacteria? I also have a clown who looks fine and a tangaroa goby who looks fine. What happened to my poor fire fish?!? He is 1.5 years old. Is there a chance he could...

Hey guys I’m new to this forum I would really appreciate some help in identifying what is affecting my clown. I got her a week ago from my lfs. From the beginning I noticed that her tail was a little ragged, but I assumed it was from other fish nipping at the store. However since then it’s...

Hi, I just bought a clownfish two hours ago from petco and recently put him in my tank. When I got him into the tank I noticed that his fins looked a little deteriorated. At petco he was in a larger tank with 2 other clownfish and a cleaner shrimp. I was wondering if someone knew what is wrong...
