  Bi-scalar CFT from $\gamma$ deformed $\cal N$=4 SYM describes the fishnet
theory which is integrable in the planar limit. The holographic dual of the
planar model is the fishchain model. The derivation of the weak-strong duality
from the first principle was presented in a recent paper (The Holographic
Fishchain arXiv:1903.10508). In this note we extend the investigation to the
tri-scalar CFT which raises from the large twist limit of ABJM theory. We show
that it becomes tri-scalar fishnet theory in planar limit and the dual theory
is the holographic bi-fishchain model.
