Hi,
I've got a 50 gallon tank with 2 fancy goldfish, the moor and a "miniature butterfly koi".
Recently the black moor (bovril) has only been active when food is in the tank, the rest of the time he/she sits on the bottom, head towards the gravel with tail upwards. Most of the time completely motionless. Other three fish are happy as anything and really active, only bovril seems to be under the weather.
Any ideas?
