Lattice Butterfly Fish for Sale: What Makes This Patterned Fish So Rare?

Have you ever seen a fish that looks like it was hand-drawn? The Lattice Butterfly Fish has a body covered in a fine crosshatch pattern that looks almost too detailed to be real. It is bold, elegant, and not something you come across in every saltwater tank. Dr. Reef’s Quarantined Fish carries this species and currently lists it at $69.99 on drreefsquarantinedfish.com.

What Is the Lattice Butterfly Fish?

The Lattice Butterfly Fish, scientifically known as Chaetodon rafflesii, is also called Raffles’ Butterflyfish. It is native to the Indo-Pacific, found across the reefs of Indonesia, the Philippines, Fiji, and the Great Barrier Reef. The body is predominantly yellow with dark edges on each scale that form a precise lattice or crosshatch pattern across the flanks. A bold vertical black bar runs through the eye, and a bright blue patch sits above it on the forehead. A dark band crosses the tail.

This combination of colors and pattern is what makes it look like something sketched by an artist rather than produced by nature. It grows to around 6 to 7 inches at adulthood and belongs to the family Chaetodontidae, the butterflyfish family.

Quick Specifications

What Makes It Rare?

The Lattice Butterfly Fish is not rare in the sense that it is impossible to find. The rarity comes from several factors combining at once. First, the Indo-Pacific reef systems it comes from are not always easy to access for ethical collection. Second, the species has specific dietary needs that make transport survival lower than hardier butterflyfish. Third, its reputation as not reef safe means fewer reef-focused stores carry it.

The result is a fish that looks unusual, arrives in good health less often than it should, and tends to disappear from stock quickly when it does appear. Dr. Reef’s Quarantined Fish holds each specimen through a full quarantine cycle at their Tulsa, Oklahoma facility before listing it, which is exactly why their specimens last.

Lattice Butterfly Fish Care Requirements

Tank Size

A minimum of 90 gallons is needed for a single adult. The species is an active swimmer that patrols open water and needs room to move. Cramped tanks cause stress, and a stressed butterflyfish stops eating fast.

Water Parameters

• Temperature: 72 – 78°F
  
• Salinity: 1.020 – 1.025
  
• pH: 8.1 – 8.4
  
• Ammonia and Nitrite: 0 ppm
  
• Nitrate: Below 20 ppm for stable color and health

Tank Setup

Provide live rock with caves and open swim lanes. This species is bold once acclimated and will actively explore. It is not as shy as some butterflyfish, which makes it interesting to watch. Keep a secure lid because it can jump if startled.

Diet and Feeding

The Lattice Butterfly Fish is a carnivore. In the wild it feeds on coral polyps, small invertebrates, and zooplankton. In captivity, feed it:

• Frozen mysis shrimp
  
• Chopped seafood such as clam, mussel, and squid
  
• Frozen brine shrimp enriched with vitamins
  
• High-quality marine pellets once conditioned

Feed two to three times daily in small portions. This species does not do well with once-daily large meals. It grazes throughout the day by nature.

Is It Reef Safe?

No. The Lattice Butterfly Fish will nip at soft corals, stony coral polyps, zoanthids, feather dusters, and anemones. It belongs in a fish-only with live rock system or a FOWLR tank where the live rock is there for structure rather than coral display. If your main goal is keeping corals, this is not the species for you. If your goal is a beautiful, boldly patterned fish in a community FOWLR system, it is an excellent choice.

Tankmates

The Lattice Butterfly Fish is peaceful toward most species. Good tankmates include:

• Larger tangs and surgeonfish
  
• Angelfish of similar or larger size
  
• Peaceful wrasses and hawkfish
  
• Cardinalfish and dartfish

Use caution with other butterflyfish that have similar patterning. Two bold-patterned butterflyfish in the same tank can develop territorial friction.

Why Quarantine Matters for Butterflyfish

Butterflyfish are among the most transport-sensitive fish in the marine hobby. They stop eating under stress, and a fish that refuses food for a week after arrival is already in decline. The quarantine process at Dr. Reef’s keeps each Lattice Butterfly Fish in a clean, stress-reduced holding system for several weeks, conditioning it to prepared aquarium foods and monitoring it for disease before it ever ships to a customer.

At $69.99, this is a professionally prepared specimen. Most unconditioned butterflyfish sold online are a gamble. This one is not.

Quick Q and A

Q: How hard is the Lattice Butterfly Fish to keep?

A: Moderate. It is hardier than obligate coral feeders but still needs consistent feeding, good water quality, and a peaceful tank. Get those right and it is rewarding to keep.

Q: Can it be kept with other butterflyfish?

A: Sometimes, in large tanks of 150 gallons or more. Avoid pairing it with species that have similar coloration or pattern. Introduce both at the same time to reduce aggression.

Q: Will it harm my invertebrates?

A: Yes. Ornamental shrimp, tube worms, and small crabs are at risk. This species is best kept in fish-only systems without expensive invertebrates.

Q: Where can I buy a healthy Lattice Butterfly Fish?

A: Dr. Reef’s Quarantined Fish at drreefsquarantinedfish.com is one of the most reliable sources for quarantined, conditioned marine fish in the hobby.
