My flame hawk when I came back home from school I found him collapsed on the ground and I thought he was dead. Now, I was gonna throw him out but I realised his gills were moving. I tried to pick him up to examine him and he had kind of a spasm. I bought him yesterday and the lfs had him for a couple of days. Doing the tests right now so I’ll update with parameters. I do not have any copper. There also might not be enough aeration maybe. His gills seem to be a bit red.
