Cobalt Blue Discus
Symphysodon aequifasciatus
No freshwater fish commands the reverence of a perfectly kept discus. Known universally as the King of the Aquarium, the genus Symphysodon has inspired generations of aquarists to master soft-water husbandry, refine their feeding regimens, and design tank environments that showcase these disc-shaped cichlids in all their chromatic glory. The Fish Collection's discus collection features hand-selected fish — from the electric Cobalt Blue Diamond to the painterly Pigeon Blood — each bred in the soft, acidic conditions that produce the deepest color saturation and cleanest patterning. Discus are not beginner fish, and we make no apologies for saying so. They demand stable water chemistry — a temperature range of 82 to 86 degrees Fahrenheit, a pH between 5.5 and 6.8, and near-zero nitrogenous waste. They require multiple small feedings per day of high-protein food: beef heart blends, frozen bloodworms, and quality pellets formulated specifically for discus. They are social fish that thrive in groups of six or more, meaning a proper discus display starts at 75 gallons and scales up from there. What you receive in return for this commitment is a living aquarium centerpiece of unparalleled beauty — a fish that recognizes its keeper, feeds from your hand, and displays color so intense it seems impossible for a freshwater animal. Every discus in our inventory has been quarantined for a minimum of twenty-one days — longer than our standard protocol — because discus are uniquely susceptible to internal parasites and hexamita infections that can be asymptomatic during shorter observation periods. We treat prophylactically, verify appetite and coloration stability, and transition each fish to a feeding schedule that mirrors what a conscientious keeper will maintain at home. When a discus leaves our facility, it is eating aggressively, displaying full color, and conditioned for the stress of overnight transit. Shipping discus requires meticulous temperature control. These fish cannot tolerate drops below 78 degrees Fahrenheit without risk of stress-induced disease. We use heavy-duty heat packs, double-insulated containers, and route-specific weather calibration to maintain stable tropical temperatures throughout transit. Our 100% live arrival guarantee applies without reservation — if your discus does not arrive in perfect condition, we replace it or refund in full.
