“…Social groups are comprised of pairs, or of a single male and varying numbers of females (Donaldson 1986b(Donaldson , 1990, which can be replaced by facultative monogamy in some obligate coral-dwelling species (Donaldson 1989). Pairspawning occurs sequentially in groups at around sunset (Thresher 1984, Donaldson 1986b, 1987, 1990, Donaldson & Colin 1989, Tanaka & Ohyama 1991, Tanaka & Suzuki 1991.…”

SynopsisWe examined the gonads of eight species in five genera of hawkfishes. Histological preparations of ovaries and testes produced evidence for protogynous hermaphroditism in Neocirrhites armatus and suggested that hermaphroditism may also be expressed in Cirrhitichthys oxycephalus, C. aprinus and C. falco, and possibly also by other species. Sexual patterns in hawkfishes are discussed in relation to environmental and ecological factors which influence mobility and length of spawning season.

“…In the present study, we examined the potential of alternative egg-guarding care in female D. reticulatus through rearing experiments. In both captive and natural conditions for mating pairs of D. reticulatus, female caretaking behaviors have never been observed when males are present (Sakanoue & Sakai, 2019, 2022Schwarz & Smith, 1990;Tanaka, 1999). This is partially because egg-guarding males often drive females out of their nests after spawning (Schwarz & Smith, 1990;Tanaka, 1999).…”

“…The sex change of females is socially controlled by dominant males of local colony groups (Sakanoue & Sakai, 2022). After laying eggs, males alone guard and care for the eggs at the nest until they hatch (Sakanoue & Sakai, 2019, 2022; Tanaka, 1999). The males exhibit egg‐caring behaviors, including “mouthing behavior,” in which they gently touch the eggs with their mouths to remove defective eggs and debris, and “fanning behavior,” in which they agitate the water around the eggs with their caudal and pectoral fins (Allen, 1991; Tanaka, 1999; Thresher, 1984).…”

The potential for egg‐guarding care in females of the damselfish, Dascyllus reticulatus, in the absence of uniparental male care

Male damselfish typically demonstrate uniparental egg‐guarding care in nature. Potential plasticity in sexual behavior has recently been reported in various teleost fish. To examine behavioral plasticity in parental care, we conducted aquarium experiments to explore the potential for egg‐guarding care in the female damselfish, Dascyllus reticulatus. After initial caretaking, males were removed from the mating nests, and cohabiting females frequently exhibited egg predation on the same day. However, we confirmed that females showed significantly decreased egg‐predation frequencies on the following day and showed egg‐caring behaviors. All experimental females guarded their eggs until they hatched. Females subsequently spawned eggs as females even after performing parental care behaviors, indicating no progression of sex change into males. Molecular analysis of select pituitary gland hormones indicated that egg‐caring females and males showed high expression levels of prolactin, suggesting its involvement in the development of parental care behaviors. The cryptic possession of caretaking ability in females may be a tactical response to the need for temporary replacement of the care roles in cases where caretaking males are removed, for example, through predation, in damselfish species living in sexually cohabiting groups.

“…Despite their importance in aquarium, butterflyfish have not received the necessary attention, and research in captivity is scarce. Captive breeding has been carried out in some species as Forcipiger flavissimus (Madden & May, 1977), Chaetodon nippon (Suzuki et al, 1980), Chaetodon modestus (Tanaka et al, 2001) and Chaetodon miliaris (Degidio et al, 2017) and the comparison between captive and wild spawning in Chaetodon nippon (Suzuki et al, 1980), Chaetodon aculeatus, Chaetodon capistratus (Colin, 1989), Chaetodon multicintcus (Lobel, 1989), Chaetodon trifascialis (Yabuta & Kawashima, 1997) and Chaetodon modestus (Tanaka et al, 2001). As for C. striatus, the gametogenesis of males and females has recently been described (Bayona-Perez et al, 2020), being fundamental for the future production of the species.…”

The hight extractivism of marine fish to supply the demand of the aquarium market has worried the researchers and, in this context,, the aquaculture consists of an alternative to the problem. The family Chaetodontidae represents one of the main families of ornamental marine fish and has not received enough attention on their cultivation research. Considering the absence of this information about the butterflyfish Chaetodon striatus, the present work had the objective of obtaining information about the species in captivity. The fishes were kept in tanks of 100, 200, 300 and 1,000 L, with 6 fishes in each tank, with 3 repetitions for each volume, totaling 72 individuals and were observed for 30 days, being offered living small invertebrates and frozen and fresh mussels for the feeding. Also, for the attempt of reproduction in captivity, two couples, collected directly from the sea, with the entry of only two adults in the trap at a time, were used. Each couple was acclimated in a 100 L tank and we observed their behaviors for 8 hours a day. There was no mortality in tanks of 300 and 1,000 L and, for feeding, small invertebrates and fresh mussels were well accepted. Some behaviors were observed, most of which were already described for chaetodontids. This is the first report of C. striatus in captivity and this contribution may provide subsidies for a future technological package.
