These are sponge with tunicates and harmless filter feeders

These are Bi-valves often referred to as clams and are related to scallop family and are filter feeders, not long lived

Ty! I guess they were a hitchhiker as well …why don’t they live long he’s so cool looking

because they feed on plankton and other elements found in the wild and the supplements we offer dont meet their needs long term. I have 6 and one made it close to a year. Fish also try to pic at them which too stresses them

Generally rock and favor low flow, low light areas of tank

These are just sponges. Tunicates are not particularly common and sponges can extend off the rockwork in "tubes" like this.

Bivalvia is a class that comprises a whole host of two-shelled mollusks: clams, scallops, mussels, oysters, cockles, etc.

Hitchhiker bivalves are longer lived than many other bivalves. As @vetteguy53081 mentioned, they feed on plankton, specifically phytoplankton. Many phytoplankton supplements can be purchased online if you want to directly feed them, though I have also heard multiple success stories of keeping hitchhiker bivalves without direct feeding.

I have one of those little bivalves, they tend to come in on wild zoa rock etc. I've had it for years, no need to feed it, it just live off general particles in the water column etc.
