This week I got 3 ADF from a friend. They have been doing pretty well from all I can tell. I woke up this morning and went check my tank as usual and noticed raised white dots on my frogs. From a quick google search it seems like a bacterial infection. I’ve been having problems with this in my tanks. My betta looks like he has fin rot also so something is majorly off. What could be causing this bad bacteria? Do I need to change my filter media? Also how do I treat the frogs? Should I do a full tank treatment with my betta in it since he’s been having problems too or do they need to be quarantined? I’ll add a picture in case I got the diagnosis wrong. It’s not my frogs but they look the same.
