The Spider Sponge, Trikentrion flabelliforme, features white horizontal lines over a striking red body. Its tree-like base is covered by a white web-like polyp colony. It is a peaceful organism that should not be housed with aggressive species of fish or inverts. If threatened, it may release a toxin that can harm other tank mates. 

The Spider Sponge should never be exposed to open air and should be kept in a large aged tank as they are filter feeders and can consume a large amount of particulates in a short amount of time. Feed them tiny foods such as marine snow,phytoplankton and zooplankton 2-3 times per day.
