How to Aquascape for a Shrimp Display Contest
Shrimp contests in Singapore and across Asia judge not just the quality of the shrimp but how they are displayed — and a mediocre aquascape can sink an otherwise championship-grade colony. Knowing how to aquascape for a shrimp display contest means designing a backdrop that showcases your shrimp’s colour, pattern and movement without distracting from them. Gensou Aquascaping has supported local contest entrants with layout advice for years, and the principles that win trophies are more nuanced than many hobbyists realise.
Contest Judging Criteria
Most shrimp contests score on shrimp quality (colour intensity, pattern definition, body shape) and display presentation (layout aesthetics, cleanliness, overall impression). The display typically accounts for 20-40% of the total score depending on the event. Judges notice cloudy water, algae, messy hardscape and poor plant health — all of which suggest subpar husbandry. A clean, intentional aquascape signals expertise and elevates the perceived quality of your shrimp.
Tank Size and Format
Contest display tanks are usually standardised — 30 cm cubes or 45 cm cubes are the most common formats in regional competitions. Some events provide uniform tanks; others let entrants bring their own within size limits. If you have a choice, a 30 cm cube concentrates the viewer’s attention and makes a smaller colony of 15-20 shrimp look abundant. Larger tanks require more shrimp to avoid appearing sparse, which increases cost and risk.
Choosing a Background Colour
Background colour dramatically affects how shrimp appear. Crystal Red Shrimp and Taiwan Bee varieties with red and white patterns pop against dark green plants and black backgrounds. Dark shrimp (Crystal Black, Black King Kong) show better against lighter substrates and pale hardscape. Before finalising your layout, hold a few shrimp in a clear container against different background samples. The contrast difference between a dark and light background can be startling — and judges notice immediately.
Substrate and Hardscape for Shrimp Presentation
Active buffering substrates (ADA Amazonia, SL-Aqua, Benibachi) maintain the acidic, soft water Caridina shrimp require while providing a dark, uniform base that enhances red and white colouration. Avoid multi-coloured or coarse gravel that creates visual noise behind your shrimp. For hardscape, select one or two small stones with clean lines — Seiryu stone or mini landscape rock — positioned to create focal points without dominating the tiny tank. Small pieces of driftwood with moss attached add natural texture.
Plant Selection for Maximum Impact
Plants serve two roles in a contest display: aesthetic backdrop and functional grazing surface. Mosses are the contest aquascaper’s best friend — Christmas moss, flame moss and weeping moss create rich green textures that contrast with shrimp colours. Attach moss to stones or wood in neat, trimmed formations. Bucephalandra species add dark green, compact foliage with interesting leaf textures. Avoid fast-growing stems that require trimming during the contest period; the layout must look pristine on judging day without last-minute maintenance.
A single well-placed Anubias nana ‘Petite’ on the main stone adds a clean focal accent without overwhelming the miniature scale.
Water Clarity and Conditioning
Crystal-clear water is non-negotiable. Run a small sponge filter paired with activated carbon for at least two weeks before the event. Perform 10-15% water changes every other day in the lead-up to the contest using remineralised RO water (TDS 130-150 ppm for Caridina). Avoid any substrate disturbance, feeding changes or new additions in the final week — stability is paramount. Some competitors run a UV steriliser for the last 48 hours to eliminate any residual bacterial bloom or green water haze.
Shrimp Behaviour and Presentation
Well-designed aquascaping encourages shrimp to graze openly rather than hide. Surfaces angled toward the viewer — a moss-covered stone tilted slightly forward, for instance — present shrimp to judges in their best light. Avoid deep caves or dense background thickets where shrimp disappear. Feed sparingly in the days before the event; slightly hungry shrimp are more active and spread across the tank foraging, rather than clustering in a corner digesting. Time your feeding so shrimp are actively moving during judging hours.
Transport and Setup on Contest Day
If you are transporting the display to a venue, bag the shrimp separately and carry the tank with hardscape and plants intact. Drain the water to just above substrate level, seal the top with cling wrap to prevent sloshing, and transport on a flat, padded surface. At the venue, refill slowly with pre-prepared water at the correct temperature and TDS. Acclimate shrimp using drip method for 30-45 minutes before releasing. Allow at least 2-3 hours for the tank to settle and shrimp to calm down before judging begins. A rushed setup shows — and judges in Singapore’s competitive shrimp scene will notice every detail.
