surveys. This is particularly beneficial when attempting to count small, inconspicuous larvae of species such as S. splendidus (Zeng et al., 2014). The 9-L tank is simpler to construct and operate than the 3-L design (Refer to Appendix B, Table B1 for approximate build times), and allows for simple, non-invasive visual inspection oflarval health, behaviour and survival, and gentle replacement of old water and live prey. The 3-L and 9-L tanks were successfully used in experiments that focused on refining the feeding regime of later larvae ofM. atrodorsalis (8–30 days post hatch) and long-term larval rearing pilot studies of S. splendidus.
