“…Only eight individuals of Heteractis crispa were observed at all southern sites combined, resulting in an abundance of 0.88 AE0.74 individuals per site (range¼0^2) or 0.09 AE0.08 per 1000 m 2 (N¼9 sites). In the northern Red Sea, individuals of Heteractis magni¢ca are rare, and were observed only near an area termed 'anemone city' at Ras Mohammed and a few kilometres further north at Ras Ghazlani (Brolund et al, 2004; Figure 1).…”

Individuals of H. magni¢ca are rare, but when present they may host ¢sh of all sizes in large aggregations such as at 'anemone city' in the southern Sinai (Brolund et al, 2004). In contrast, individuals of the anemone H. crispa host juvenile ¢sh (A. bicinctus), while individuals of E. quadricolor contain both juveniles and adults (Fishelson, 1970;Fricke, 1974).…”

patterns of distribution and abundance of giant sea anemones and anemonefish were compared among coral reefs along the coastline of sinai in the northern red sea. the sea anemones varied widely in abundance between reef areas containing different habitat types. they were rare on steep reef slopes with abundant coral cover (=low-density anemone sites, 0.09–0.68 anemones per 1000 m2 of reef area), but were common at a site containing patch reefs interspersed with sand (=high-density anemone site, 6.00–8.11 anemones per 1000 m2). distributions of the endemic two-band anemonefish (amphiprion bicinctus) varied significantly between the two main host anemone species. at the high-density site, individuals of the sea anemone heteractis crispa either did not contain anemonefish, or were occupied by single juvenile fish as shown in previous studies. at low-density sites h. crispa usually hosted clusters of juvenile anemonefish. in contrast, individuals of the sea anemone entacmaea quadricolor hosted either single adult fish (high-density site) or pairs of breeding adults (low-density sites), frequently in addition to some juvenile fish. mechanisms that prevent anemonefish from reaching adult size and forming breeding pairs in h. crispa may include high fish mortality above a size threshold because this host cannot adequately protect them from predation when they become large, active emigration of fish to e. quadricolor as described in previous reports, and/or environmentally-controlled cessation of fish growth. we conclude that in the northern red sea, individuals of h. crispa potentially serve as nurseries for anemonefish.

The Heteractis magnifica assemblage at the tip of the Sinai Peninsula was examined. The actinian size, location, and number of resident anemonefishes were recorded. The anemones were found at depths down to approximately 40 m and the sizes of clustering H. magnifica and clusters were positively correlated with depth. The shallow waters of the anemone assemblage contained few mainly small, solitary actinians. There seemed to be a tendency for solitary actinians to cluster once they reached a certain size-range. The resident anemonefishes Amphiprion bicinctus and Dascyllus trimaculatus were present in very large numbers (approximately 250 and 1800 respectively) and the A. bicinctus home range size was positively correlated with depth.

“…Vision is believed to be an important sensory system in environments where water clarity is typically high, as on coral reefs (McCormick & Manassa 2008, Huijbers et al in press). Overall, the visual system of fish is well developed (Guthrie & Muntz 1993), and previous studies have shown that fish can distinguish habitats (Lecchini et al 2007b) and conspecifics (Brolund et al 2003) by use of visual cues. However, little attention has been paid to the possible additive effects of habitat structure and presence of conspecifics in visual habitat choice by marine fishes.…”

Habitat selection by coral reef fish is influenced by a variety of biological and abiotic factors, but the relative importance of these factors is expected to change throughout ontogeny, especially for species that utilize different habitats during their life cycle. In this study, 2 in situ choice experiments were designed to test the individual as well as the interactive effects of habitat structure and schooling (with conspecifics or heterospecifics) on refuge-seeking behavior of a coral reef fish. The experiments were conducted for 3 size-classes of the common reef fish Haemulon flavolineatum, a species that shows multiple habitat shifts throughout its ontogeny. We tested the hypothesis that, due to the additive effects of schooling and structure in providing suitable refuge, fish would be more attracted to a microhabitat with conspecifics or heterospecifics than to a microhabitat or conspecifics alone. In the habitat-only experiment, early juveniles (< 3 cm fork length) showed no preference for any microhabitat structures, whereas larger fish preferred complex mangrove structure to seagrass, rubble, or coral. In the second experiment, which offered various combinations of habitat, including habitat with both conspecifics and heterospecifics, the preference for mangrove structure was completely replaced by attraction to conspecifics for all size-classes. Unexpectedly, the combination of conspecifics and habitat structure showed no additive effect. The results demonstrate that although H. flavolineatum makes multiple shifts in habitat throughout its life cycle, in the absence of other biological or environmental drivers preference for shelter habitat past the early post-settlement stage remains the same. The study further demonstrates the critical role of the presence of conspecifics in microhabitat choice, and provides a better understanding of the relative importance of these factors, whether in isolation or additively, in selection of refuge habitat by a reef fish.
