Hi everyone, Just found this in my tank sorry for the bad pic cant get a good shot of it, looks like some sort of filter feeder, is like a tube shape tapers in to a point attaching to rock, other end looks to have a hole in the middle and has bright glowing marks around the hole when marine blues are on.

It looks like some type of worm. Maube OF2F or Kells have seen something like it.

I was reading an invertebrate book, when I randomly stumbled upon a page that reminded me of this thread. I am pretty sure it is a Crystal Tunicate. Google doesn't help, because it doesn't specify the name. Here is the Scientific Name:Clavelina Robusta.

They look like sea squirts.

This is what the book says.

One of the few species of colonial tunicate available in the aquarium trade, albeit sporadically. Many do not survive the rigors of collection and shipping. However, if their specific demands are met in the home aquarium, they can prove hardy and long-lived. The rings around the siphons can be yellow, green, or white.

WHAT Size?

Each individual animal achieves around 2.75-3.25 inches (7-8 cm) in height and about .04 inches (10 mm) in diameter. Colonies can number several hundred individuals, but most of those imported for the aquarium trade are much smaller.

WHAT does it eat?

Consumes fine particulate material, including phytoplankton and suspended bacteria. To meet the animal's long-term nutritional requirements, provide slightly larger-particulate foods; oyster eggs, rotifers, and similar formula diets are more suitable.

WHERE is it from?

Tropical Indo-Pacific

HOW compatible with other inverts?

As with other encrusting organisms that reproduce asexually, good growth in healthy colonies can mean competition for substrate. But it presents little direct threat to neighbors.

WHAT water flow rate

Indirect flow is best for most individuals.

HOW much light

Appears to prefer lower-light situations, but can thrive in an aquarium with high wattages of metal-halide lighting, providing it is kept free of fouling algae.

WILL it threaten fish?
