Fishing Tower Defense Fish Rarity Tiers Explained

Learn which Fishing Tower Defense rarities to sell, keep, trait-roll, or chase with premium bait and incense.

Last updated:

Every catch in Fishing Tower Defense arrives with a rarity tier that shapes sell value, trait investment, and whether the fish deserves a permanent tower slot. supreme stu’s Roblox hybrid (Place 73598910647444) ties power to what you fish — so understanding rarity language stops you from burning Premium Dice on junk and selling the one uncommon that actually held your choke point.

This guide is the roster filter for best starters, Devil Whale, how to get extincts, and the tier list hub. Exact UI colors follow the live client; community names below match how players talk in Discord.

Rarity ladder (player language)

TierTypical jobDefault action
CommonTutorial fillerSell / release after early slots fill
UncommonTemporary coverageKeep only for missing roles
RareEarly–mid backboneKeep role fits; consider trait rolls
Epic / LegendaryMid anchorsKeep; prioritize dice if traits dead
Extinct / chase headlinesLate spikes & flexPlan hunts; never impulsively sell

Chase names such as Devil Whale sit at the top of attention even when your account still needs basic splash coverage — do not let flex override wave strategies.

Commons and uncommons

Commons exist to teach the loop. Once you can place four towers and clear early waves, sell them for Credits (currency). Keeping twenty commons blocks inventory during better bait sessions (how to fish).

Uncommons can temporarily cover a missing role. Promote them only if traits are surprisingly strong. Otherwise they are Credit fuel on the way to early-game tier list rares.

Rares — where most accounts live

Rares are the workhorses:

  • Build first permanent slots from best starters
  • Match roles in tower roles
  • Spend free 500kVISITS dice here before chasing extincts
  • Replace only when a higher tier with equal or better traits arrives

A rare with a damage amp often beats a legendary with empty rolls. Read traits and dice before every Premium Dice click.

Epics, legendaries, and August newcomers

Mid and high tiers become relevant when mid waves demand more HP burn. After the August 2026 update, new units may enter these brackets — re-test before you assume July rankings still apply (current meta, late-game).

Investment rules:

  1. Confirm the unit fills a real hole (splash, range, utility, carry DPS)
  2. Roll traits only on keepers
  3. Place on correct tiles (lane map tips)
  4. Upgrade with Credits from clean clears, not panic shop buys

Extinct and headline chases

Extinct-tier and viral chase fish (including Devil Whale content) need planned sessions:

Never empty your account for one color tier if your lanes still leak.

Keep vs sell vs trade matrix

Keep — role fit + acceptable traits + you still need that job.

Sell — duplicate commons/uncommons; dead-trait extras after roster complete.

Trade — headline duplicates when friends need them; use rare trades and trusted Discord contacts only.

Hold for project — high base species waiting on one more trait roll.

Bait spending by rarity goal

GoalBait approach
Fill early rosterCheap/standard bait; clear waves often
Upgrade raresMix standard + selective premium
Chase extinct / Devil WhalePremium bait + incense; hard stop-loss
Test August new unitsOne focused premium session, then evaluate

Bait economy details: items hub and the 650+ bait grind mindset in community videos — volume without a goal still wastes Diamonds.

Co-op rarity etiquette

Do not ninja every rare node during a shared incense window. Call targets, split duplicates fairly, and keep wave defense staffed (co-op waves).

Fair play

Rarity farms via macros or exploit tools risk bans — scripts hub. Manual fishing only.

FAQ

Frequently Asked Questions

Quick answers to the most common questions.

Should I keep common fish in Fishing Tower Defense?

Only while learning. Sell commons once you can fill early tower slots with better rarities.

Are rares good enough for mid waves?

Yes when roles and traits are complete. Many accounts clear mid content without extincts.

When do I spend Premium Dice?

On keepers you already want — usually strong rares and higher — not on random commons.

Do new August units change rarity value?

They can. Re-test newcomers for role fit before selling July keepers with good traits.

Is extinct always better than legendary?

Often stronger, but placement and traits still decide real DPS. A dead-trait extinct can disappoint.
