Hello , I think it would be very helpful if some or all of the veiltail breeders and experienced veil keepers would go into detail about how they over winter there fish . Such as , do you give them a winter rest period , if so how long ? If you do a winter rest period , what temperature do you try to maintain ? Also water changes and feeding ? If you don’t use a rest period for your fish , what do you do different than say your summer routine ? I think this is the most difficult time period for goldfish keepers .
