How big does Randall's Assessor grow?\u003c\/p\u003e\n\u003cp\u003eIt is a relatively small marine fish, generally reaching around 5–8 cm depending on the specimen and source.\u003c\/p\u003e\n\u003cp\u003e3. Why does Randall's Assessor swim upside down?\u003c\/p\u003e\n\u003cp\u003eThis is natural behaviour associated with the Assessor genus. They frequently swim upside down beneath rock ledges and overhangs, where they feel comfortable and protected.\u003c\/p\u003e\n\u003cp\u003e4. Can Randall's Assessor live with other fish?\u003c\/p\u003e\n\u003cp\u003eYes. They are generally peaceful and suitable for community reef aquariums. Avoid housing them with aggressive predators or larger fish that may intimidate or outcompete them for food.\u003c\/p\u003e\n\u003cp\u003e5. What does Randall's Assessor eat?\u003c\/p\u003e\n\u003cp\u003eThey are carnivorous and should receive a varied diet of mysis shrimp, enriched brine shrimp, copepods, small marine crustaceans and quality marine pellets.\u003c\/p\u003e\n\u003cp\u003e6. Can I keep multiple Randall's Assessors together?\u003c\/p\u003e\n\u003cp\u003eThey can be territorial towards their own kind, particularly around preferred hiding places. Keeping one specimen is generally recommended unless you have a sufficiently large aquarium and carefully planned introduction.\u003c\/p\u003e\n\u003ch2\u003eCommon Mistakes\u003c\/h2\u003e\n\u003cp\u003e1. Keeping them with aggressive tank mates: Their naturally shy behaviour makes them unsuitable for aquariums containing highly aggressive or dominant fish.\u003c\/p\u003e\n\u003cp\u003e2. Insufficient hiding places: Without caves, crevices and overhangs, they may remain stressed and spend excessive time hiding.\u003c\/p\u003e\n\u003cp\u003e3. Keeping multiple specimens without planning: Assessors can become territorial towards one another, especially in smaller aquariums.\u003c\/p\u003e\n\u003cp\u003e4. Allowing larger fish to outcompete them for food: Their smaller size and shy feeding habits mean they can easily miss meals when housed with aggressive feeders.\u003c\/p\u003e\n\u003cp\u003e5. Leaving the aquarium uncovered: Randall's Assessors can jump when startled, so a secure lid is recommended.\u003c\/p\u003e\n\u003cp\u003e6.
