Hi everyone. It’s been a while since I posted. The ICH has all been dealt with. I have slowly lowered the temp back down to 76 and my lone neon tetra has been doing great for a week and a half. Water parameters are 0.25/0/20 (was 0/0/20 two days ago) so I just did a 50% water change. I will check my nitrate in a couple hours again to make sure it’s went down. Assuming it has, how many neon tetras can I safely add today?
