An indispensable member of your cleanup crew!<\/em><\/p>\n<p><strong>Overview<\/strong><br \/>\nThis striking *Calcinus elegans*, commonly known as the Electric Blue Hermit Crab, boasts brilliant blue legs adorned with bold black bands, contrasting with bright orange antennae and eye stalks. An active scavenger, it constantly explores your aquarium, sifting through sand and rocks. Its engaging behaviour and vivid coloration make it a captivating and beneficial addition to any established marine setup.<\/p>\n<p><strong>Care Level<\/strong><br \/>\nConsidered easy to care for, this hermit crab is suitable for beginners, provided stable water parameters and suitable shell availability are maintained. While generally peaceful, ensure ample space and extra shells to prevent aggression towards snails or other hermits, particularly during molting.<\/p>\n<p><strong>Tank Essentials<\/strong><br \/>\nA minimum aquarium size of 50 litres is recommended for a single specimen to allow adequate foraging space. Maintain stable water parameters with a pH range of 8.1\u20138.4 and a temperature of 22-28\u00b0C. Provide a variety of empty snail shells for growth and shelter.<\/p>\n<p><strong>Diet<\/strong><br \/>\nAs an omnivorous detritivore, the Electric Blue Hermit Crab primarily grazes on various algae, including nuisance hair algae and cyanobacteria, and consumes detritus and uneaten food. Supplement their diet with quality marine pellets, algae wafers, and occasional small meaty foods.<\/p>\n<p><strong>Why Buy From Us<\/strong><br \/>\nWhen you buy Electric Blue Hermit Crab online from us, you receive healthy, responsibly sourced invertebrates.
