I’ve had this group of 6 neons for almost 2 months now. They came to me as a surrendered tank along with a betta who has since passes. Now it’s just the 6 of them in a 10 gal. They have bright red gills, and are more pale in color. I did two rounds of antibiotic treatments with kanaplex and Furan-2 as I assumed it was bacterial. I also did one round of prazipro in case it was flukes. Nothing has worked. They have stayed the same and I haven’t lost one yet. One has a crooked spine which looked like NTD but still no losses after months. They eat well and are active. I have another school of 8 healthy neons in my 16 gal that are soon going into a 72. I really want to combine them but not if something is up with their health. I just moved and moved the tank so all parameters are 0 currently but it was cycled before and I kept the substrate and media wet the entire time. I believe it should have kept the cycle but I’ll monitor it.
