I’m not sure what happened to his Finns and I need help to find out exactly what the issue is and ways I can help treat him. He lives in a 2 gallon filtered and heated tank with gravel and fake plants. He does have one rock that is slightly sharp with a live plant living on top. I’ve also noticed he got these brown dots on the top of head and body that weren’t there before. Are these just apart of his coloring changing or is it a symptom of another issue? Thanks and let me know as soon as possible!!
