{"product_id":"pearly-calvis","title":"Pearly Calvus","description":"\u003cp\u003eThe pearly calvus (Altolamprologus calvus) is a Lake Tanganyika cichlid built like a blade — extremely compressed side to side, with heavy scaling and a sloping head that lets it push into narrow rock cracks after prey. It hangs almost motionless in the water, then moves suddenly. Growth is famously slow, so a small fish stays small for a long time, and patience is part of keeping one.\u003c\/p\u003e\u003ch2\u003eAquarium care\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAdults can reach 12 to 13 cm, but take years to get there.\u003c\/li\u003e\n\u003cli\u003eNeeds hard, alkaline water and stacked rockwork with narrow crevices.\u003c\/li\u003e\n\u003cli\u003eA predator of small fish, fry and shrimp — anything that fits in the mouth is food.\u003c\/li\u003e\n\u003cli\u003eCalm and unaggressive toward fish too large to eat.\u003c\/li\u003e\n\u003cli\u003eTakes quality pellets and frozen foods; feed with restraint given the slow growth.\u003c\/li\u003e\n\u003cli\u003eSpawns in shells and tight crevices.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGood in a Tanganyikan community with other rock dwellers of similar or larger size.
