Olive green fancy long tailed goldfish

Olive green fancy long tailed goldfish My pond is slightly overstocked and all my normal goldfish have been sold ,now I have these long fined goldfish that move elegantly in water due to their long tails. Only olive green colour for sale, a few may stay olive green but most will change colour in the future to yellow,orange,red or a mix with black.They are about 10-15cm long ,they are being sold at pet stores for £15+ each ,comment then pm if interested.
