I have 3 tinfoil barbs that are bleeding through their scales...
One parrot fish on its side. And one silver dollar that was found upside down but still alive I see as 10% chance of survival
. I did a big water change. Before doing the change I took some readings.. I thought it might of been something to do with the ammonia but surprisingly the ammonia was at 0? PH was a 6.0 I usually have it at 6.5. Nitrites 0, Nitrates <10
