25 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 23-07-2020.

A single solo shore entry dive by Gary of 250 minutes. Maximum depth 5.9 m, 18 C water temperature up to 8 m viz.

A Melbourne kind of winter day! The water is still quite clear and this is the first time in 3 years the water temp has dipped to 18C. Some very interesting nudibranchs were recorded today, some we have not seen since the big flush-out. Thuridilla carlsoni, Philinopsis speciosa x2 and Tenellia sp. 62 were great to see come back! On a different note Goniodoridella sp. 1 has all but dried up, only 2 animals were recorded.
