Fish Index, Luck, and Size Tags in Hole Fishing
Understand what the index tracks, why luck rises, and how Large Huge Giant tags fit mutations.
The fish index in Hole Fishing is your long-term collection and luck engine. Filling new species entries quietly improves how often valuable outcomes appear, while size tags like Large, Huge, and Giant change how much weight and cash each catch demands. This guide stays honest: we do not invent a complete species table or fake percentages.
What the fish index is
The index tracks species you have successfully landed. Each new name is progress toward broader luck benefits that stack with rod luck. Think of it as a checklist that rewards curiosity after every hole or rod upgrade — not a Pokédex you must finish in one night. When a bite looks unfamiliar, finish the hold carefully; a Too strong fail on a new name wastes an index chance as well as cash. Pair recovery with the Too strong fix if weight is the blocker.
Luck benefit (without fake math)
Players and creators consistently treat index progress as a luck power spike. Exact formulas are not published here because we will not invent them. Practically:
- More unique species → better odds of interesting rolls over long sessions
- Rod luck and index luck stack toward mutations and specials
- Night play and the Night rod amplify windows where index hunting feels productive — see night and secrets
If two rods are close in price, prefer weight when you fail heavies, or luck when you land everything but rarely see new names or mutations.
Incomplete species list honesty
Public play and videos mention names such as Betta, Koi, Crocodile, Shrimp, Octopus, Seahorse, Turtle, Sawfish, Swordfish, plus standouts like Orfish, Void ray, Ancient turtle, and Legendary toadfish. That list is illustrative, not complete. Hole Fishing can add or rebalance species after patches. We will not publish a fake full catalog. When you discover a new name, log it mentally, sell smart, and check updates if the shop or branding shifted.
Avoid copying Ice Fishing Simulator or Fisch / Fish It bestiaries — different games, different pools.
Mutations and the index
Mutations are special variants that sell for more. Index luck helps the whole special-catch economy, including mutations. Deep mutation behavior lives on the mutations page. Do not skip new base species just to chase a shiny you saw in a video; filling commons and mid fish still raises the luck floor that makes specials more frequent over time.
Size tags: Large, Huge, Giant
Size tags sit on top of species names:
- Large — first step up; needs enough hole size and rod weight
- Huge — mid premium size; fails more often on weak rods
- Giant — top size pressure; classic Too strong bait if you over-expanded the hole
Bigger tags usually mean better sells when they land. They also punish rod neglect. After a hole upgrade, fish long enough to register new sizes and species before rushing the next purchase — a habit also stressed in common mistakes.
Session habits that fill the index
- After each rod or hole buy, cast for a focused stretch instead of menu shopping.
- Sell full bags so you keep casting instead of walking mid-discovery.
- Prep Night rod and bag before dusk for unusual rolls.
- Enter server hole windows with weight ready so new names actually land.
- Track cash goals with how to make money so index hunting does not bankrupt Magma savings.

Frequently Asked Questions
Quick answers to the most common questions.
What does the fish index do in Hole Fishing?
It tracks species you have landed and contributes luck that stacks with rod luck toward better and more special catches over time.
Is there a complete species list on this wiki?
No. We only cite publicly seen examples. The live game may include more species; we will not invent a full catalog.
Do Large, Huge, and Giant count separately in the index?
Treat size tags as modifiers on species that raise weight and sell value. Confirm live UI behavior in your build; focus on landing them with enough rod power.
Should I hunt the index or rush Magma?
Do both in parallel: keep rod and hole balanced for cash, and spend focused cast stretches after upgrades to register new names.
How do secrets relate to the index?
Secret rarity is a high-end outcome helped by luck systems including index progress. See Night and Secrets for prep without fake drop rates.
