Cells like algae and protists avoid lysis in freshwater through various mechanisms, primarily osmoregulation. They possess contractile vacuoles that expel excess water that enters the cell due to osmotic pressure, preventing swelling and bursting. Additionally, their cell walls or membranes may provide structural support and help maintain internal pressure without compromising the integrity of the cell. Some also utilize solute accumulation to balance osmotic pressure and stabilize their internal environment.
Fresh water algae may struggle to survive in a saltwater environment due to differences in salinity levels. The saltwater will cause water to move out of the cells of the freshwater algae, causing them to shrink and potentially die.
Algae can grow in both fresh and saltwater environments, but some species are better adapted to one or the other. Saltwater algae, or seaweed, have evolved to thrive in high salt concentrations, while freshwater algae can be found in ponds, rivers, and lakes. Both types of algae require nutrients, light, and water to grow effectively.
Euplotes are found in fresh water algae!
Volvox is a genus of green algae that form colonies shaped like hollow balls and live in fresh water. Each colony consists of hundreds or thousands of individual cells that work together for functions like reproduction and movement.
As larger eukaryotic cells many can be seen under a light microscope ( moderte to good quality ). Simple fresh pond water can show a whole different world of protists.
Red tides are caused by single celled algae that belong to the protists. Wikipedia doesn't list what phyla single cell algae are in. But they are phylum "Cyanobacteria"

you buy an algae fish at a pet store to eat the algae.

The fresh water green algae (charales), can reach up to 120 cm long. Hope that helps.
Protists that are classified as animal-like are called protozoans and share some common traits with animals.All animal-like protists are heterotrophs. Likewise, all animal-like protists are able to move in their environment in order to find their food.Unlike, animals, however, animal-like protists are all unicellular. The are all eukaryotes.Fungus-like protists are heterotrophs with cell walls. They also reproduce by forming spores. All fungus-like protists are able to move at some point in their lives. There are essentially three types of fungus-like protists: water molds, downy mildews, and slime molds.Plant-like protists are autotrophic. They can live in soil, on the bark of trees, in fresh water, and in salt water. These protists are very important to the Earth because they produce a lot of oxygen, and most living things need oxygen to survive.Furthermore, these plant-like protists form the base of aquatic food chains. These plant-like protists can be unicellular, multicellular, or live in colonies. The plant-like protists are divided into four basic groups: euglenoids, dinoflagellates, diatoms, and algae.
Rabbit fish are herbivores and primarily feed on algae, seaweed, and other plant matter. They graze on surfaces using their specialized teeth to scrape off algae. In a home aquarium, their diet can be supplemented with algae wafers and blanched vegetables.
