With a clear dividing line down the middle, the front half ranges from brown to blue while the back half transitions into a bright orange-yellow, giving this little fish a look that genuinely earns its common name. \u003cem\u003eEcsenius pulcher\u003c\/em\u003e, the closely related Elegant Blenny, shares the same split-colour concept with a slightly deeper, more vivid variation on the theme and identical care requirements. Both species bring the same winning combination: a bold personality, a fondness for perching out in the open where everyone can see them, and a genuine appetite for nuisance algae that makes them pull their weight in any reef system.\u003c\/p\u003e\n\u003ch3\u003eWhy we love it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStriking two-tone colouration that stands out beautifully against reef rockwork\u003c\/li\u003e\n\u003cli\u003eActive, curious personality that quickly becomes a favourite in any tank\u003c\/li\u003e\n\u003cli\u003eNatural algae grazer that helps keep rockwork clean between maintenance sessions\u003c\/li\u003e\n\u003cli\u003eHardy and beginner friendly; one of the most approachable marine fish in the hobby\u003c\/li\u003e\n\u003cli\u003eEndlessly entertaining perching and hopping behaviour throughout the aquascape\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSuggested parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTemperature: 24 to 26°C (75 to 79°F)\u003c\/li\u003e\n\u003cli\u003eSalinity: 1.025 to 1.026 SG\u003c\/li\u003e\n\u003cli\u003epH: 8.1 to 8.4\u003c\/li\u003e\n\u003cli\u003eAlkalinity: 8 to 10 dKH\u003c\/li\u003e\n\u003cli\u003eCalcium: 400 to 450 ppm\u003c\/li\u003e\n\u003cli\u003eMagnesium: 1250 to 1400 ppm\u003c\/li\u003e\n\u003cli\u003eNitrate: 5 to 20 ppm\u003c\/li\u003e\n\u003cli\u003ePhosphate: 0.03 to 0.12 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and temperament\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDifficulty: Easy\u003c\/li\u003e\n\u003cli\u003eTemperament: Peaceful toward most tankmates; territorial toward other blennies and similarly shaped fish\u003c\/li\u003e\n\u003cli\u003eReef safe: Yes, with the note that occasional nipping at LPS corals or clam mantles may occur if the fish is underfed, but this behaviour typically stops with adequate feeding\u003c\/li\u003e\n\u003cli\u003eMinimum tank size: 30 gallons with plenty of live rock\u003c\/li\u003e\n\u003cli\u003eA mature, established tank with a healthy crop of algae already growing on the rockwork is strongly preferred; in a new sterile system without a functional ecosystem a bicolour blenny can struggle to find enough to eat\u003c\/li\u003e\n\u003cli\u003eA tight-fitting lid is absolutely essential; these fish have strong flight reflexes and are confirmed jumpers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDiet\u003c\/h3\u003e\n\u003cp\u003eThe Bicolour Blenny is primarily herbivorous and algae access is the foundation of its health.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNaturally grazes algae from live rock and tank surfaces throughout the day\u003c\/li\u003e\n\u003cli\u003eNori and dried seaweed sheets on a clip\u003c\/li\u003e\n\u003cli\u003eSpirulina-based pellets and flakes\u003c\/li\u003e\n\u003cli\u003eFrozen herbivore blends\u003c\/li\u003e\n\u003cli\u003eFrozen mysis shrimp, brine shrimp, and finely chopped krill are also accepted as supplemental meaty foods\u003c\/li\u003e\n\u003cli\u003eIf algae growth in the tank is insufficient, more frequent feeding and algae-rich supplemental foods such as spirulina are essential\u003c\/li\u003e\n\u003cli\u003eFeed twice daily; keeping this fish well fed is the single most important factor in preventing any territorial or coral-nipping behaviour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and tankmates\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExcellent with clownfish, small wrasses, dartfish, shrimp gobies, and most peaceful reef community fish\u003c\/li\u003e\n\u003cli\u003eCan be territorial toward other blennies, small gobies, dartfish, and fish with similar body shapes or colour patterns such as Royal Grammas and Bicolour Pseudochromis\u003c\/li\u003e\n\u003cli\u003eKeep only one per system unless a confirmed mated pair in a larger tank\u003c\/li\u003e\n\u003cli\u003eAggressive species like triggers, large puffers, or groupers will stress or potentially eat a bicolour blenny and should be avoided\u003c\/li\u003e\n\u003cli\u003eGenerally ignores shrimp, snails, and other ornamental invertebrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHealth and acclimation notes\u003c\/h3\u003e\n\u003cp\u003eThe Bicolour Blenny is one of the hardiest and most forgiving marine fish available, making it an excellent choice for intermediate and experienced hobbyists alike. A drip acclimation of around an hour is recommended, and the fish should not be introduced to a tank without sufficient algae growth for it to graze on between meals. Ensure rockwork is stable and well-supported, as bicolour blennies are active diggers and will frequently move rubble, sand, and small debris around the base of the aquascape.\u003c\/p\u003e\n\u003ch3\u003eWhat you are buying\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eYou will receive: 1 Bicolour Blenny (\u003cem\u003eEcsenius bicolor\u003c\/em\u003e or \u003cem\u003eEcsenius pulcher\u003c\/em\u003e)\u003c\/li\u003e\n\u003cli\u003eSpecific species and colour intensity can vary between individuals; both species share identical care requirements\u003c\/li\u003e\n\u003cli\u003eMales are generally larger than females and can display colour shifts including blue during breeding condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSlow acclimation is recommended.
