Flame Scallop (Lima scabra) is a marine invertebrate kept by aquarists for reef-tank cleanup, biological control of pests, or aesthetic display. Demanding requirements make this species best for keepers with established mature systems and proven track records.

Where Flame Scallop comes from

Flame Scallop (Lima scabra) is native to Indo-Pacific reef ecosystems, with wild populations distributed across coral reefs, sandy lagoons, and rocky tide pools. Captive specimens are typically wild-collected; some species are starting to be aquacultured but most Flame Scallop sold today still comes from wild reef collection. Sustainable sourcing matters - look for vendors who can verify their collection practices, and consider aquacultured alternatives when available.

Flame Scallop tank size and setup

Flame Scallop requires a minimum of 30 gallons for healthy adults. The minimum is based on the species' adult size (4 inches), territorial range, and behavior pattern. Most Flame Scallop sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.

For a Flame Scallop setup: mature reef tank with stable parameters, live rock for cover, sandbed substrate (1-2"), reef-grade lighting if photosynthetic, and a fully-cycled biological filter at least 6 weeks old. Newly-cycled tanks under 6 weeks crash the parameters that Flame Scallop depends on.

Water parameters for Flame Scallop

Flame Scallop requires standard reef parameters held tightly stable:
Temperature: 76-80°F (24-27°C)
Specific gravity: 1.025 (refractometer-measured)
pH: 8.1-8.4
Alkalinity: 8-9 dKH
Calcium: 420-450 ppm
Magnesium: 1300-1400 ppm
Ammonia + nitrite: Both 0 ppm
Nitrate: Under 10 ppm
Copper: 0 (lethal to invertebrates)

Flame Scallop is sensitive to copper - never medicate the display tank with copper if Flame Scallop is present. Stable parameters beat perfect parameters.

What Flame Scallop eats

Flame Scallop is a plankton filter feeder. Filter-feeds on suspended plankton and dissolved organics. Target-feed live phytoplankton, rotifers, or commercial reef foods (Reef Roids, Coral Frenzy) 2-3x weekly to ensure adequate nutrition. Feed Flame Scallop appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.

Flame Scallop tankmates and compatibility

Flame Scallop is generally peaceful and compatible with most reef community species. Avoid keeping with predatory fish that view inverts as food: large wrasses (especially halichoeres + thalassoma), triggerfish, pufferfish, and certain large angelfish. Multiple Flame Scallop can share a tank but compete for food.

Flame Scallop adult size and lifespan

Flame Scallop reaches 4 inches at adulthood with a captive lifespan of 1-3 years with proper care. Many marine inverts molt periodically; provide adequate calcium and a stable parameter regime to support healthy molts.

Can you breed Flame Scallop?

Flame Scallop breeding in captivity ranges from straightforward (some shrimp, snails) to nearly impossible (most starfish, urchins) due to pelagic larval requirements. Captive-bred specimens are increasingly available from sustainable aquaculture facilities; check with vendors before assuming wild-caught origin.

Common Flame Scallop diseases and problems

Flame Scallop is sensitive to copper, ammonia spikes, low oxygen, and rapid parameter swings. NEVER use copper medications in a tank with Flame Scallop. Symptoms of stress: reclusive behavior, color loss, refusal to feed, abnormal molting (incomplete or stuck molts). Most Flame Scallop deaths trace back to acclimation shock or parameter mismatch - drip-acclimate over 45-60 minutes when adding to a new tank.

Deep-dive Q&A on Flame Scallop

Answers to the questions experienced keepers ask after the basic care guide.

How long does Flame Scallop take to acclimate to a new tank?

Drip acclimation over 60 to 90 minutes is the safest approach for Flame Scallop. Match temperature first (15 minute float), then drip 2 to 3 drops per second from the display sump until the bag volume has tripled. Test salinity (or freshwater hardness) at the end - if it is within 0.001 SG (or 2 dGH) of the display, transfer the specimen with a net rather than pouring shipping water in.

What is the best filtration setup for Flame Scallop?

Aim for biological + mechanical + chemical staging. Canister or sump-driven filtration sized for 5x to 8x display turnover per hour, mechanical floss replaced weekly, and carbon or GAC swapped every 4 to 6 weeks. Flame Scallop responds well to stable nitrate (under 20 ppm) more than to any specific filter brand - stability beats peak performance.

Does Flame Scallop need a protein skimmer?

For saltwater specimens, yes - a properly-sized skimmer rated for 1.5x to 2x display volume keeps dissolved organics low and reduces nuisance-algae triggers. Freshwater specimens do not need skimmers; a well-stocked plant grow-out + canister with chemical media achieves the same end. Flame Scallop kept without adequate organic export tends to show stress within 90 days.

Can Flame Scallop be kept in a planted tank?

Compatibility with planted tanks depends on the species behavior + water chemistry overlap. Plant-safe specimens leave foliage alone; some pick at soft-tissue plants like vallisneria or anubias. Check the species page profile + the planted-tank compatibility note before stocking Flame Scallop in a high-tech CO2-injected setup with valuable cultivars.

What is the ideal lighting for Flame Scallop?

For freshwater specimens with no plant requirements, a basic LED at 30 to 50 PAR at substrate is sufficient and reduces algae. For saltwater + reef specimens, target 100 to 250 PAR depending on photo-tolerance, with a sunrise/sunset ramp + a 8 to 10 hour photoperiod. Flame Scallop tolerates a wider lighting band than most keepers expect; consistency matters more than peak intensity.

Does Flame Scallop prefer high or low water flow?

Most aquarium species evolved in moderate flow with localized turbulence rather than uniform high flow. Aim for 20x to 40x display turnover for reef specimens, 4x to 6x for community freshwater. Flame Scallop shows stress fins (clamped, frayed) when flow is mismatched - dial back if you see this within 14 days of introduction.

What temperature shift will stress Flame Scallop?

Sustained drift above +/- 2 F from target is the threshold most keepers miss. Flame Scallop tolerates day-night swings of 1 to 2 F without issue but a 4 F shift over 2 hours triggers ich + bacterial bloom risk. Use a controller-driven heater (not the built-in dial) and a backup thermometer at the opposite end of the tank.

What are the top 3 diseases that hit Flame Scallop the most?

For freshwater fish: ich, columnaris, and fin rot are the top three; quarantine + UV sterilizer prevents the majority. For marine fish: ich (Cryptocaryon), velvet (Amyloodinium), and bacterial infections; tank-transfer method or copper QT during the 30-day acclimation cycle prevents nearly all outbreaks. For inverts + corals: tissue necrosis, parasitic isopods, and protozoan blooms.

Can Flame Scallop be bred in captivity?

Captive breeding success varies enormously by species - some breed readily in community tanks (livebearers, cherry shrimp, clownfish) while others have never been captive-bred (most reef fish + most marine inverts). Check the species-specific care guide for the breeding-method note + larval-rearing protocol. Flame Scallop kept in pairs or small groups often spawns even without intent if conditions are right.

What are the best tankmates to avoid for Flame Scallop?

Avoid same-species rivals (especially male-male pairings for territorial species), known fin-nippers (tiger barbs, certain pufferfish), and anything that out-competes for food or out-grows the tank. Flame Scallop also struggles with hyper-aggressive cichlids in freshwater and damselfish in saltwater - both will hold territory at the expense of every other tankmate.

Is Flame Scallop safe to keep with cleaner shrimp or cleaner wrasses?

Most ornamental specimens accept cleaner shrimp + cleaner gobies; cleaner wrasses (Labroides) often die in captivity and are not recommended. Flame Scallop kept with cleaner pairs typically benefits from parasite control + stress reduction, but verify the cleaner does not get eaten by checking the species size + temperament chart.

What is the realistic lifespan of Flame Scallop with proper care?

Captive lifespan tracks closely to wild lifespan when water chemistry, diet, and tankmate stress are managed. Most aquarium fish live 5 to 12 years; long-lived species (large cichlids, pufferfish, some tangs) reach 15+ years. Flame Scallop kept in a stable, properly-sized system should live within 80% to 100% of the species lifespan ceiling - early death usually traces back to chronic-stress causes (parameters, tankmates, diet) rather than disease.
