I have just rescued two fancy goldfish, Dennis and Colin, from a relative.
They were kept in a tiny 25L tank (Dennis was there just under a year, Colin was there a few months). They were only sporadically fed and with flakes, and had about 10-20% of their water changed per week.
They are now in a 50L interim tank (they'll soon move to a 140L tank as my other fish have outgrown it). I change 80% of their water daily, and they get sinking pellets and peas everyday.
Apart from being severely stunted, missing some scales and with a black patch on a fin, I have noticed they both have a weird twitch as they swim along. It is very sudden and jerky; it looks to be neurological, as if they have brain or nerve damage. They swim fine apart from this twitch.
Does anyone have ideas on the cause, and what I might do in addition to the current regime?
My theory is over-exposure of toxic water in their previous home, along with malnutrition.
I would welcome any thoughts.
