The Fish Detour Task Apparatus recreates the published four-compartment aquatic task in which a subject observes a social goal through a window, exits a central corridor, and chooses among compartments near or far from that goal.
Paper-defined two-tank system
The validated reference is a pair of physically separate glass tanks facing each other, with their adjacent walls left uncovered. A custom corridor-and-partition insert can be evaluated only after the laboratory supplies the exact internal tank dimensions. The final drawing confirms every aperture, barrier, divider, water depth, tank alignment, and mounting interface.
Source-backed multi-species geometry
The published apparatus was used with zebrafish, goldfish, redtail splitfin, and freshwater angelfish. Species-specific husbandry and study procedures remain under the laboratory protocol.

Practical Tips
Match water depth and the two adjacent viewing walls.
Why: The source setup creates a continuous view between subject and goal tanks.
Provide the base-tank internal dimensions before ordering an Insert Kit.
Why: Aperture and divider positions depend on the usable internal tank geometry.

Background reading relevant to this product:
Was this apparatus used with zebrafish?
Yes. Zebrafish were one of four freshwater species tested in the published apparatus.
What is the difference between the complete system and a custom insert?
The complete system follows the paper-defined two-tank relationship. A custom insert is not assumed compatible and is quoted only after the base tank dimensions and viewing geometry pass engineering review.
How many choice compartments are there?
Four: two near the social goal and two on the opposite side of the experimental tank.
Does the apparatus include recording equipment?
The choice area supports overhead recording. Camera and analysis systems are configured separately.
