Info

Botryllus schlosseri (Pallas, 1766)

Botryllus schlosseri is an invasive species of ascidian with an almost worldwide range. The zooids, which measure only a few millimeters, form colonies that have a distinct star-shaped arrangement of the individual animals. This arrangement makes it easy to distinguish them from the otherwise similar Botrylloides species. They occur in varying colors.

Not much is known about husbandry, like with other hitchhiking ascidians the tank biology decides if these animals can be kept or not. Special feeding isn't normally practiced.
