Few aquarium choices are simpler than a mixed goldfish selection. "Mixed" here means assorted Carassius auratus — colours and forms vary from fish to fish, which is half the appeal for keepers who enjoy variety without picking specimens one by one. What never varies is the constitution underneath: an easy-care, peaceful cold-water fish with real staying power, living around ten years and capable of reaching 25 cm at full size. For a first serious cold-water tank, that combination of hardiness and unpredictable colour takes a lot of beating.
That adult size is the number to respect. Allow at least 120 litres of cool water between 15 and 25 °C, with pH 6.5–8.0 and hardness of 10–30 dGH. Goldfish use the whole aquarium rather than one layer, so prioritise open swimming room over dense decoration, and cater for an omnivore's varied diet when you plan feeding. A tank sized for the adults from day one saves the upgrade scramble that catches out so many goldfish keepers in their first year.
Compatibility could not be plainer: house them with other goldfish of similar size and type, and stop there. Small tropical fish, species needing warmer water, fin-nippers, aggressive fish and very small invertebrates all belong in a different system. Within their own kind they are thoroughly peaceful — the temperament holds across the group, so squabbling is rarely an issue when sizes are matched — and the easy care rating makes this listing a practical first step into cold-water fishkeeping. The recorded chemistry window of pH 6.5–8.0 is comfortably wide, which takes much of the anxiety out of weekly testing.

A note before ordering
Because this is an assorted listing, order expecting variety rather than one specific colour or form — that unpredictability is the point. A mixed selection also makes practical stocking for a new large tank, since every fish in the bag shares identical care requirements. Fish are sent to UK addresses by licensed live-animal courier with a live arrival guarantee on every box.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
