20 x Primary Skittle Shrimp – Red, Blue, Yellow & Orange Neocaridina Mix – Ayr Aquatics

20 x Primary Skittle Shrimp Red Blue Yellow Orange – Bred in Ayr, Scotland

Our Primary Skittle pack is a bold four-colour mix of Neocaridina davidi shrimp in Red Cherry, Blue Diamond, Yellow Golden Back and Orange Sakura, with no browns, blacks or patterned shrimp. It gives you the brightest, cleanest rainbow you can put in a planted tank. Every shrimp is home-bred by Ayr Aquatics in Ayr, South Ayrshire from our own graded colonies.

This listing is for a pack of 20 Primary Skittle shrimp, our best value per shrimp. The 20-pack is for keepers who want a colony up and running fast, are stocking a larger tank of 40 litres or more, or want to start a breeding project with good genetic variety. With twenty shrimp you get a strong mix of males and females and plenty of breeding pairs, and the price works out cheaper per shrimp than our smaller packs.

Colour and grade

We pick as even a split of the four colours as possible: a 20-pack is five of each, and a 10-pack is balanced as closely as the numbers allow (three of two colours, two of the others). The shrimp come from the same lines we sell as single-colour packs, so you get properly solid reds, deep glossy blues, bright yellows and vivid oranges, not washed-out culls.

Why choose Primary Skittle shrimp?

Red, blue, yellow and orange are the four colours that stand out most against green plants, so this pack gives the biggest visual impact for a display, aquascape, office or children's tank. It is also a great way to find out which colour you love most before committing to a single-colour colony.

Breeding a mixed colony: All four colours are the same species, so they will interbreed. The first generations give a fun mix of babies, and over time the colony drifts towards brown, wild-type colour. To keep the colours bright, top up with fresh shrimp now and then, or move your favourite colour into its own tank.

Caring for your Primary Skittle shrimp

Add them to a fully cycled tank only, with zero ammonia and nitrite. Shrimp are sensitive to copper, so check any plant fertilisers or medications before using them. Use dechlorinated tap water and do small, regular water changes of 10–20% a week rather than large ones. Moss, plants, cholla wood and Indian almond leaves give them biofilm to graze on and hiding places when moulting. Feed a quality shrimp food every day or two, in amounts they finish within a couple of hours, plus the occasional blanched vegetable.

Acclimatisation

Float the bag for 20–30 minutes to match temperature, then drip-acclimatise slowly over 1–2 hours before netting the shrimp into the tank. Do not pour the bag water into your aquarium. Keep the lights low for the first day and do not worry if they hide at first. That is normal.
