Oxbow water with rotten leaves collected a month ago.
Collection from a pond in a local park, cultivation in a laboratory tank and the microscopic observation thereof. These are ideal conditions to keep Daphnia in a tank: pH 7-8.6; O2d >6mg/L; hardness 160-180mg CaCo3/L; and light 16hr. light/8hr/dark. Feed them on pond algae.
2mm long. Very very flat body. Shown here under dissecting scope.
Larva of a Phantom Midge (Family: Chaoboridae) identified in a bag of 'Daphnia' collected from a local pond facility in the West Midlands, UK.
Tanked Cyclopoid Copepods, namely Acanthocyclops vernalis. These were found included with Daphnia sp. and therefore care needs to be taken when using these tiny creatures for microscopic study, so as it avoid any confusion.
I think this came from the water in a lab colony of something, so I have absolutely no idea where it was collected.
