The species lists of scleractinian hard corals in Peninsular Malaysia have not been updated for 15 years. The present study aimed to determine the diversity and abundance patterns of scleractinian hard corals at twenty eight fringing reef sites along the coast of Redang and Tioman Islands. Visual photograph analyses of the coral video transect method revealed a total of 128 species from 47 genera in Redang and 239 species from 55 genera in Tioman. Following recent taxonomy of scleractinian corals, coral surveys and past studies revealed a total of 166 species from 53 genera in Redang and 350 species from 67 genera in Tioman. Current data at both islands presented a total of 358 species from 69 genera and 15 families of scleractinian corals with an additional 8 new species records for the east coast of Peninsular Malaysia. Acropora, Montipora and Porites were the most dominant genera and were found distributed within the coral assemblages. The reefs around both islands can be categorized under “good” coral conditions with the live corals cover from 40.9% to 73.5%. Overall findings indicated that the less affected reef zones by coastal development and human activities at both islands have established good coral conditions and coral genera diversity.

Previous studies indicated that artificial live rock (ALR) has the potential to be used as a substrate for coral juveniles. The present study reported a potential of ALR as an ideal substrate for future artificial reef structure. This study was conducted at three sampling sites, namely Teluk Salang, Teluk Bakau and Teluk Sanggit in Tioman Island, Pahang, Malaysia. The total of 96 samples of ALR (n = 48) and terracotta tiles (n = 48) were deployed and periodically retrieved with three-month interval for 15 months. Retrieved settlement plates were analyzed to compare the total abundance of epibionts and coral density between ALR and tiles. Results showed that ALR plates exhibited a significantly higher total benthic abundance compared to terracotta tile [Independent T-Test; t (22) = 2.650, p = 0.015]. On average, a total of 82.8 ± 5.2% of benthic organisms covered ALR’s surfaces compared to terracotta tiles with 62.5 ± 5.6%. The number of coral spats was significantly higher on ALR by 60.7 ± 10.7% compared to terracotta tiles [Mann–Whitney U Test; U = 10.5, p = 0.003]. In addition, there was a significant difference between sites in the abundance of epibionts as determined by one-way ANOVA [F (2,21) = 11.945, p < 0.001] for both substrates. However, Kruskal–Wallis H test showed that there was no significant difference in terms of coral density at the sites of deployment [H (2) = 3.730, p = 0.155]. The results demonstrated ALR as a new suitable settlement substrate for benthic organisms which can be applied as a substrate for artificial reef, coral propagation and coral transplant.
