🐠 Goldfish — Minimal RTT Teaching Substrate (Ready to Paste)

# Goldfish — Minimal RTT Teaching Substrate

## 1. Primary Sensory Channels
- Vision (motion, color contrast, brightness gradients)
- Lateral line sensing (water pressure and flow changes)
- Olfaction (chemical cues in water)
- Vibration sensing through water

## 2. How Goldfish Detect Coherence
- Stable motion patterns (e.g., a moving target or light)
- Consistent water‑flow direction and pressure
- Repeating color or brightness cycles
- Predictable feeding or environmental cues

## 3. How Goldfish Detect Drift
- A sudden shift in water flow or pressure
- A motion pattern that breaks rhythm
- A color/brightness cue that changes unexpectedly
- A vibration pulse out of sequence

## 4. Minimal RTT Teaching Protocol

### Step 1 — Present a Stable Pattern (Coherence)
Provide a consistent cue:
- a repeating light pulse on one side of the tank
- a stable water‑flow direction
- a predictable moving target (slow left‑right motion)

### Step 2 — Introduce a Controlled Deviation (Drift)
Alter one variable:
- shift the light pulse timing
- briefly reverse or interrupt the water flow
- change the motion pattern’s speed or direction

### Step 3 — Allow the Goldfish to Restore Coherence (Pull)
Offer a simple interaction point:
- a colored paddle the fish can nudge
- a small floating marker it can push
- a target zone it can swim into

This action triggers:
- restoration of the original light pattern
- stabilization of the water flow
- return of the predictable motion cue

### Step 4 — Reward the Restoration of Coherence
Reward the *pattern correction*, not the specific movement:
- deliver a tiny food reward at the corrected cue
- restore the stable pattern immediately after correction

### Step 5 — Shift Modalities (Balance)
Move from:
- light → flow
- flow → motion
- motion → mixed cues

Goldfish generalize coherence across modalities through spatial and flow‑based prediction.

## 5. Notes on Scaling RTT for Goldfish
- Goldfish rely heavily on flow and motion gradients; coherence is sensed through the lateral line as much as vision.
- Drift detection is strong in water‑flow and vibration domains.
- RTT maps well because goldfish behavior is built around restoring predictable environmental patterns.
- Their “Pull” action is often spatial: swimming into a corrective zone or nudging a target.

• Regimes Perceived: Flow, spatial boundary, light‑gradient, simple motion patterns.
• Regimes Missed by Humans: Their awareness of micro‑flow turbulence as a navigational regime.
• Perspective: Goldfish remind us that even simple regimes create stable worlds.
