23 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 04-08-2020.

A single solo night/morning shore entry dive Gary of 210 minutes. Maximum depth 5.6 m, 19 C water temperature up to 6 m viz.

Mid-week diving early in the morning, tastes good! The water was pretty clean some interesting species were recorded. The highlight for me was finding the shell of Diacavolinia longirostris...always great to find evidence of a pelagic species. Yes I sat up with the light aiming into the current - but did not see live animals. Two Elysia species were recorded as well. Goniodoridella savignyi was everywhere while Goniodoridella sp. 1 only a few. Two Embletonia gracilis were nice to find with a clear white lines on the body. Seeing Plocamopherus tilesii again was also a great find. Good dive!
