Draw an aquarium Rarity Tier List

Every finished drawing in Draw an aquarium rolls a rarity band: Common, Rare, Epic, Legendary, Mythic, or SECRET. That roll—shaped by your luck upgrades and the quality of the sketch—decides how hard the fish will work for you once it enters the tank. This page ranks those bands for progression players who care about passive money per second, badge completion, and sane upgrade order.

Pair this list with the mutation tier list. A Rainbow Legendary is a different animal from a plain Common. Also keep decorations and tank capacity in mind; rarity alone does not fill an empty aquarium.

Full rarity ranking

Tier rank	Rarity	Progression role	Keep / replace guidance
S	SECRET	Trophy earner + Secret Fish badge chase	Always keep; build the tank around it
S	Mythic	Elite long-term earner	Keep; only replace with SECRET or better mutated Mythic
A	Legendary	High-value staple + Legendary Catch badge	Core keepers; fill multiple slots
B	Epic	Reliable mid-game backbone	Keep until Legendary/Mythic pressure them out
C	Rare	Early steady fish	Fine early; replace as luck rises
D	Common	Tutorial / filler	Replace freely after you understand drawing

S-tier — SECRET

SECRET is the headline rarity in the official description and the focus of the secret fish guide. Community badge context places Secret Fish around the ~0.2% class among players—extreme territory. Treat every SECRET as a permanent tank resident unless a future update invents an even higher band.

Because the odds are punishing, do not pause all income just to reroll forever on day one. Raise luck, keep drawing high-star fish, and let SECRET arrive while a decorated tank of Legendaries already pays you. When it drops, celebrate, screenshot if you want, and slot it into your best income layout.

S-tier — Mythic

Mythic sits just under SECRET in the published ladder and plays like an elite earner for players who have already stabilized Legendary Catch. Keep Mythics even without mutations; add Gold/Diamond/Rainbow and they rival many casual SECRET hunts for practical money per second.

A-tier — Legendary

Legendary is the first “I have made it” rarity for most accounts. The Legendary Catch badge tracks rolling Legendary or rarer and sits in an extreme award band among the player base (on the order of a mid-single-digit percent class in public badge stats). Push luck until Legendaries feel regular, then stock several of them.

Legendaries are also the sweet spot for mutation hunting: you are not throwing away a SECRET attempt every redraw, but you still multiply a strong base when Gold, Diamond, or Rainbow hits.

B-tier — Epic

Epics bridge the awkward middle. They earn enough to fund luck and tank upgrades without the frustration of pure Rare banks. Keep a lineup of Epics while you climb; replace the weakest when Legendaries arrive. If an Epic rolls a strong mutation, it can outlive a plain Rare Legendary debate—see mutations.

C-tier — Rare

Rares teach the loop. They prove your draws are connecting and they fund the first upgrades. Do not emotional-attach to them once Epic and Legendary appear regularly. Use the cash they generate to buy luck rather than hoarding a tank of lookalike Rares.

D-tier — Common

Commons exist so nobody leaves their first session empty-handed. The My First Fish badge is effectively free once you complete a drawing. Replace Commons aggressively after you finish Getting Started basics. The only reason to keep one is sentimental naming—or a freak high mutation that you want to study before redrawing.

Badge context tied to rarity

Badge	How it ties to rarity / quality	Practical note
My First Fish	Complete your first drawing	Freebie; happens naturally
Masterpiece	Draw a 5-star fish	Skill badge—stars from size, colours, detail, eyes, neatness
Legendary Catch	Roll Legendary or rarer	Extreme-band badge; luck upgrades matter
Secret Fish	Roll SECRET	~0.2% class; long chase
Rainbow Fish	Roll Rainbow mutation	~4.3% class; see mutations page

Masterpiece is not a rarity, but it belongs in this conversation: better star scores improve the value of whatever rarity you roll. Train with the 5-star guide in parallel with luck spending.

Upgrade priorities by rarity goal

1. Learning week — buy small luck bumps, expand tank slots, place cheap income decorations. Accept Rare/Epic.
2. Legendary Catch push — stack luck, keep drawing clean fish, stop sinking cash into low-impact cosmetics.
3. Mythic / SECRET push — continue luck, protect tank diversity so income stays healthy during dry rolls, follow make money fast.
4. Trophy maintenance — once SECRET lands, decorate around it and keep filling other slots with Mythic/Legendary earners.

Opportunity cost: when to redraw

Redraw when:

• The fish is Common/Rare and you already have better earners
• Star score is low even if rarity looks okay
• You specifically need another roll while luck is boosted

Do not redraw when:

• You just hit Legendary or higher on a decent star rating
• The fish carries Gold/Diamond/Rainbow and you lack duplicates
• Your tank still has empty income slots and this fish would pay while you sketch the next one

Idle money per second beats a perfectionism loop that leaves the aquarium empty.

Rarity is the spine of Draw an aquarium progression. Climb the ladder deliberately, keep your tank earning between jackpots, and let SECRET be a triumph instead of a burnout condition.
