Hey soo I'm sorta new here and I guess I wont learn without starting a new thread. So I've had my Betta for about 6 or 7 months now, and when I got him he had small black spots on him that I thought were just his markings. But now, I noticed that they're starting to appear all over him. I'll try to post some picture of it. Any thoughts on what it could be? My betta is also a silver-blue color, so its really noticeable.
Edit: Suzu is in a 2.5 gallon tank, but thats going to change as soon as I move out in 2 months. His tank is usually at room temperature, and has no filter or heater. He's fed once a day with 2-3 pellets. I usually change his tank water every 2 weeks, if i miss 2 weeks i do full water changes. I usually put salt with water conditioner in the water before putting in Suzu.
