The Most Famous Acropora Strains, and Where the Names Came From

Names are the hobby's memory

Collectors often ask for a Walt Disney, an Oregon Tort, a Purple Monster. Many famous names point to a colony grown and passed hand to hand through the hobby. Others cover several similar-looking corals, so the name alone is no guarantee of lineage. These are the ones that built the modern acro hobby.

Six cards trace Walt Disney to Mike Biggar, Purple Monster to Steve Shvetstoff and Steve Tyree, Oregon Tort and Red Planet to ORA records, Pink Lemonade to John Tubs Susbilla, and Strawberry Shortcake to a name credited to Joseph Caparatta.
Six documented hobby histories show how famous Acropora names spread through growers and sellers. Trade history is not proof of species, original collection locality or genetic identity; the coral silhouettes are decorative. View full size.

The headliners

Walt Disney (commonly sold as Acropora tenuis). The rainbow acro that defined an era, with blue, lavender, and lime-green colours under blue light. Grown and popularized by Mike Biggar of BigR Corals from a green frag bought at a West Palm Beach swap. Another headliner, Jason Fox's Homewrecker, pushed the saturation even further.

Oregon Tort (sold as Acropora tortuosa). Deep blue and famously slow, with a long Oregon hobby history. Its early import story is less certain; ORA documents receiving frags from Oregon in 2004 and beginning sales in March 2008. Another classic, Cali Tort, combines blue and green. Honest footnote: a 'tort' trade name is not a confirmed species identification; ORA lists Oregon Tort as Acropora sp.

Tyree Purple Monster. A cornerstone of the named-frag market, imported from the Solomon Islands in 1995 and grown and distributed by Steve Tyree. Reeffarmers credits Steve Shvetstoff with the name; the Limited Edition program came later. Deep solid purple, white polyps, painfully slow. Reeffarmers has labelled it Acropora valida, but that trade identification is not the same as a verified species determination. The documented lineage is the point.

Bali Green Slimer (commonly sold as Acropora yongei). The fluorescent green staghorn that coats itself in slime, grows like it means it, and has been the first acro recommendation for a generation. Keeping a Slimer is already keeping an acro, and a useful first step before trying more demanding varieties.

Strawberry Shortcake (the original Unique Corals form is sold as Acropora microclados). Pink and red over a pale green body. Unique Corals credits Joseph Caparatta with the name, inspired by his favourite frozen dessert. 'Shortcake' now gets used for several similar-looking acros, so ask which line is being offered.

ORA Red Planet (Acropora sp.). A red table acro that goes green at its base in lower light, aquacultured by ORA, Oceans, Reefs and Aquariums, whose farm raised frags put named strains in ordinary stores. ORA's line also gave the hobby Pearlberry, Hawkins Echinata with its delicate turquoise branches, and Frogskin. ORA lists all four as Acropora sp.

Tyree Pink Lemonade. Yellow to lime-green body, pink polyps, another Tyree Limited Edition, and one of the prettiest contrasts in the hobby. Reeffarmers records that John 'Tubs' Susbilla renamed the earlier Lime Green Acro Pink Lemonade; Hugo Zuniga supplied Reeffarmers' frag. JF Fox Flame, a Jason Fox signature coral, answers it in red to purple with bright yellow tips.

GARF Purple Bonsai (attributed to Acropora valida). Purple body, neon green polyps, and a bonsai growth habit, from the GARF research foundation's early aquaculture work.

A name can preserve a story. It cannot prove the identity of every frag sold under it. These examples document trade associations, not verified wild collection sites.

  • Walt Disney: Mike Biggar’s coral began as a green frag from a Florida swap. A seller’s “Walt Disney” label alone cannot verify the original line. Source 1.
  • Purple Monster: Steve Tyree grew the 1995 import. Steve Shvetstoff supplied the name. The name’s history does not establish a scientific species identification. Source 1; Source 2.
  • Oregon Tort: ORA received stock from Oregon in 2004. ORA frag sales began in 2008. This documents ORA’s stock, not the earliest wild collection site. Source 1.
  • ORA Red Planet: ORA received its first piece in May 2006. This is ORA’s acquisition date, not a verified first-release date. Source 1.

The name is only a starting point. Ask for the frag’s source and documented history. The same name does not prove the same lineage. Trade names do not confirm scientific species.

Read the fine print like a collector

Here is what separates a collector from a shopper. Many strain-to-species attributions are tentative. ORA, for example, says Pearlberry resembles Acropora desalwii but has not been positively identified. Names such as PC Rainbow, Fox Flame, and Purple Monster should be treated as hobby lineages, not species determinations. A famous name with a documented chain of hands (who grew it, who got frags from whom) is worth more than a famous name with a Latin label taped on.

That is also why two frags with the same name can look different. Light, flow, and nutrients redraw an acro's colours, and some lookalike frags in the trade are simply not the lineage they are sold as. Buy the lineage, not the photograph.

Where to start

New to acros? Start where the famous list overlaps with the hardy list: Bali Green Slimer, GARF Purple Bonsai, ORA Red Planet, and well-established millepora varieties. Learn stability on those. Alkalinity stability matters, alongside temperature, salinity, nutrients, lighting, and flow. Avoid abrupt changes and make adjustments gradually. More delicate varieties are diplomas, not homework. Build a record of stability before adding them, and ask the grower about the needs of the actual frag.
