I have back up salt from when my big tank had epilitisis but I wasn't sure it worked on possible parasites. None of the others in the tank seem affected but I do tend to get alot of Alage on the tank but someone once told me It was a good sign and my Otto have been slacking but I'll do a manual...
I noticed my keyholes forehead area color was changing so I did water change but figured it was due to stress since my beta died and they've been together for years (beta was old no signs of sickness) but then today I noticed this. What is it and how do I treat it?🥺
