Actinopteri (ray-finned fishes) > Tetraodontiformes
(Puffers and filefishes) > Monacanthidae
Etymology: Acreichthys: Greek, akre, -as = terminal, topmost + Greek, ichthys = fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 12 m (Ref. 90102). Tropical
Indo-West Pacific: Indonesia to Papua New Guinea, north to southern Japan.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 2 - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 2334)
Found among soft corals (Ref. 9710, 48637). Extremely well camouflaged when among the corals. Observed picking on the coral polyps and the coral tissue may be an important part of their diet (Ref. 48637).

Estimates based on models
Preferred temperature (Ref. 123201
): 25 - 29.3, mean 28.6 °C (based on 1725 cells).
Phylogenetic diversity index (Ref. 82804
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00939 - 0.04240), b=2.93 (2.76 - 3.10), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
