Draw an aquarium Controls Guide

Smooth controls turn Draw an aquarium from a clumsy doodle pad into a fast money machine. You will spend most of your time on the drawing canvas, then bounce between tank management, upgrades, and decoration placement. This page documents the practical input patterns for PC and mobile so you can finish fish quickly, hit better star scores, and keep every slot earning. Pair it with Getting Started for the full loop and 5-Star Fish for scoring technique.

The experience runs on Roblox with up to 7 players per server. UI scale can vary with device and Roblox settings—if buttons feel tiny, raise Roblox GUI scale or use a larger window before blaming the game.

Core loop inputs (every platform)

Regardless of device, the creative loop is the same:

1. Open the draw fish flow from the main aquarium UI.
2. Choose brush colour and size.
3. Draw the body, fins, and details.
4. Place eyes.
5. Enter a name.
6. Confirm to roll rarity (Common → SECRET) and possible mutation (Gold, Diamond, Rainbow).
7. Place the fish into an open tank slot.
8. Spend earnings on capacity, luck, and decorations.

If any step fails, cancel and restart rather than submitting a broken fish that wastes a roll opportunity.

PC controls

Drawing canvas

• Left mouse drag — paint strokes on the canvas.
• Colour picker / swatches — click to change active colour before the next stroke.
• Brush size controls — cycle small/medium/large; use larger sizes for body fills, smaller for eyes and stripes.
• Eraser / undo — remove mistakes; neatness is a star pillar, so undo early instead of layering junk.
• Confirm / Next — advances from shape painting to eyes, naming, and the rarity reveal.

Tips for PC precision:

• Fill bodies with medium-large brushes, then switch small for facial details.
• Keep the cursor inside the canvas; stray clicks outside can deselect tools.
• If you overshoot a fin, undo once instead of scribbling a corrective blob.

Camera and movement

Standard Roblox character controls still apply in the 3D aquarium space:

• WASD — move your avatar.
• Mouse — look / orbit depending on camera mode.
• Space — jump if the map allows.
• Shift — sprint when enabled by Roblox.

You do not need fancy parkour to progress—the economy lives in UI panels—but walking between shared showcase areas is easier when movement feels natural.

Menus, upgrades, and decor

• Click upgrade entries for tank capacity and luck.
• Open the decoration shop/catalogue, select a prop, then click a valid placement point in the tank view.
• Rotate or reposition if the UI exposes gizmo handles; otherwise sell/replace misdropped props using the manage flow described in Decorations.
• Keep the Make Money Fast priority list nearby so you do not misclick luxury cosmetics before capacity.

Keyboard quality-of-life

• Esc — closes many Roblox and experience popups.
• Enter — confirms text fields when naming fish.
• Ctrl+Z equivalents may map to in-game undo only if the experience wires it; prefer on-screen undo buttons when unsure.

Mobile controls

Drawing with touch

• Single finger drag — paint.
• Tap swatches — change colour.
• Tap brush icons — change size; thicker brushes forgive shaky aim.
• Undo button — critical on touch because palms and fat-finger edges create stray marks.

Mobile star-score advice:

• Prioritise a large silhouette and clear eyes—size and eyes are easier wins than micro-detail on a phone.
• Rest the device, use the thumb for broad fills, and switch to a fingertip edge for pupils.
• Zoom attention (not necessarily pinch-zoom) by drawing the head last when your hand is steadiest.

Touch UI navigation

• Tap HUD buttons to open draw, shop, upgrades, and codes entry if present.
• Drag carefully when placing decorations; accidental taps can buy the wrong item—confirm prices.
• If the on-screen Roblox joystick overlaps a brush UI, temporarily move your thumb zone or rotate to landscape.

Performance notes

Lower graphics in Roblox settings if stroke lag appears. Input delay causes messy neatness scores and slower money loops. A stable 30 FPS with accurate strokes beats max graphics with delayed paint.

Eyes and naming — the controls people skip

Eyes are not optional flavour; they are a scored category toward Masterpiece. On both PC and mobile:

• Enter the eyes step deliberately.
• Place two eyes at head height with similar size.
• Confirm contrast so pupils read against the body colour.

Naming:

• Tap/click the name field.
• Type with keyboard or mobile OS keyboard.
• Avoid leaving the field focused while trying to paint—finish text, then confirm.

Incomplete eye or name steps are a common reason players think “controls are broken” when they simply skipped a modal.

Tank management controls

After the rarity roll:

• Select an empty slot or a replace target.
• Confirm placement so the fish starts earning money every second.
• Review the tank occasionally; sort mentally by rarity and mutation using rarities and mutations.

Never end a session with a finished fish stuck outside the tank—that is free income left on the table (Make Money Fast).

Upgrade panel habits

• Open upgrades with a dedicated HUD button (wording may be Upgrade / Shop / Tank).
• Buy capacity while slots are empty.
• Buy luck when the tank is full and you want better rolls toward Mythic/SECRET (Secret Fish).
• Double-check costs; mis-taps on mobile are expensive.

Decoration placement controls

• Select a decoration from the catalogue.
• Tap/click the tank volume to place.
• Adjust position if handles exist; keep props from blocking your view of high-value fish if the camera angle matters to you.
• Prefer money-boosting decor first—full strategy on Decorations.

Codes and external panels

If the experience includes a codes button, open it, paste carefully (mobile paste long-press), and submit. Keep the live list on the codes page. For patch-driven UI changes, read updates. Official place links live on the links hub.

Accessibility and comfort

• Increase Roblox UI scale for small phones.
• Use a stylus on tablets for cleaner neatness scores.
• Take breaks during long SECRET grinds; fatigue creates accidental strokes that tank star ratings.
• Colourblind players should pick high-contrast palettes so eyes and stripes remain visible—helpful for both scoring and tank readability.

Practice drill for faster controls

1. Draw five one-colour fish focusing only on speed and undo discipline.
2. Draw five two-colour fish with deliberate eyes.
3. Place each into the tank without hesitation.
4. Buy one upgrade between batches.
5. Finish with one slow Masterpiece attempt (5-Star Fish).

By the end, the draw → roll → place → upgrade loop should feel automatic. That fluency is what lets economy guides and SECRET hunts actually work.

When UI labels change after a patch, cross-check updates and the Guides Hub. Controls evolve; the need for clean eyes, full slots, and intentional upgrades does not.
