In the past 2.5 months I’ve lost 2 pearl gouramis, 2 male kribensis, 4 red banded loaches and 1 beta in my small neocardina tank which had some scale damage (that’s why I moved her- so she could heal. I thought maybe there was some drama. The scales got better mostly but then got bad again and she just died from one day to the next. No pineconing or anything)
1 gourami did look skinnier before dying but was eating and pooping.
1 kribensis looked lethargic the day before dying but was eating normally.
The rest seemed normal until disappearing including all the loaches which ate so much and were fat and active as hell.
All my tetras and amanos are absolutely fine. My raspboras and neocardina populations are thriving. What the hell is going on? Why are these fish dying randomly?? Is it parasites or something? But if so why is it not more obvious? Why no wasting? Why are their colours vibrant? Why is everyone acting totally calm and normal??? I’m sooooo confused.
