Red Algae- mostly marine, chlorophylls a and phycobilin From examination of this restricted set of data, and referring back to discussions of systematics and taxonomy, it is most likely that the most primitive algae ( ) were marine. A cross wall does form during formation of the oogonium, which separates it from the parent filament. The most common forms include gelatinous filaments, free filaments, and pseudoparenchymatous forms. All the algae except Rhodophyta (red algae) develop motile flagellated cells during some stage of their life cycles. α1-4 branched glucose polymer dispersed throughout the cytoplasm. Chinese Algae Eaters need at least 30 gallons of space with a pH of around 6.5 to 7.5 and a temperature between 74 and 80 degrees.
