Thanks a lot, it makes more sense. Now I have another Ocean green sick as well, I have been worried for the first one that just has come out for food for a few days, but not 100% recover (the colour is still dark and a bit scared).
The second one turns dark and dull colour and one of fin has white colour about 1/3 of the length. Obviously he refuses food, so scared in the corner.
And what I did yesterday night was that as per lfs I put a bag of carbon next to intake to get rid of ammo. I took it out today while I did w/c because I am thinking it could be the problem for the second one.
PH = 6.3 , ammo = 0.6.
I thought I had done every thing right at the beginning, so that I would get the healthy fish, but I only get stressed and worried problem after problem. Please tell me what I should do to fix the second one. Thanks a lot in advance.
