Through visual censuses in three climatic seasons (dry, rainy, and northerly winds) between 2017 and 2020, the analysis of seasonal and interannual variations in the abundance of fish recruits in a reef lagoon (Mahahual, Quintana Roo, México) was carried out. Temporality was analyzed using average recruit density graphs and multivariate analyses (multivariate ANOVA, ANOSIM, and RDA) to assess composition differences between year and season levels. A total of 9326 recruits were registered, belonging to 36 species and 8 fish families. The Labridae had the greatest number of recruits, followed by Pomacentridae and Scaridae. The recruits were more abundant in the dry season when the average temperatures were 27.50–27.87 °C; meanwhile, they presented a lower abundance in the northerly wind season when the temperature was lower (26.7 °C). The most abundant species was <i>Thalassoma bifasciatum</i> (138.72 recruits/100 m<sup>2</sup>), followed by <i>Abudefduf saxatilis</i> (100.05 recruits/100 m<sup>2</sup>) and <i>Halichoeres bivittatus</i> (45.94 recruits/100 m<sup>2</sup>). The multifactorial ANOVA for the average density and the ANOSIM for the composition of recruits did not show significant differences for the year factor, but they did for the season factor.

The abundance of sponge-dwelling species is expected to be heavily influenced by their degree of habitat specialization, as well as the distribution and morphology of potential host sponges. We conducted surveys along the fringing reefs of Curaçao to test how host sponge community composition and morphology drive occupancy patterns of the yellowline goby (<i>Elacatinus horsti</i>). The assemblage of goby-occupied sponges varied across the island, representing habitat heterogeneity across surveyed sites. We found <i>E. horsti</i> to be a sponge generalist, commonly occupying three species: <i>Aplysina lacunosa</i>,<i> Aplysina archeri</i>, and <i>Neofibularia nolitangere</i>, though all host species had some unoccupied sponges. A variable related to overall sponge size—maximum sponge height—significantly influenced the likelihood of goby occupancy. Goby group size in a sponge was also influenced by maximum sponge height along with the number of oscula and the species of host sponge. Specifically, group sizes were bigger in larger sponges with more openings, and the noxious sponge <i>N. nolitangere</i> hosted groups that were estimated to be 2.6–9.0 times larger than groups in other sponges when accounting for host morphology. Therefore, for these site-attached fish, the opportunity for conspecific interactions varies across different hosts.
