2. Periclimenes Brevicarpalis
Periclimenes Brevicarpalis or also named The Glass Anemone Shrimp, Pacific Anemone Shrimp, or The White-Patched Anemone Shrimp. It is sometimes hard to see within its host anemone, this creature is the most common of all the imported anemone shrimps.

They also have to slowly approach the sea cucumber and cover its body with the mucus. If there are several Glass Anemone Shrimp in the tank, the males will have the white spots and become larger than the females.

3. Neopetrolisthes Sp
Neopetrolisthes Sp or well known as The Porcelain Crab is a stunning and beautiful smaller crab. Porcelain crabs mostly have a white body with lots of red markings and black spots. Porcelain crabs can grow maximum around 1 inch and need to be kept in tanks.
Porcelain crabs are peaceful crabs. They won’t bother other inverts, coral or fishes. This makes the Porcelain Crabs addition to most reef tanks. Porcelain Crabs spend their time in a hosting anemone that keep them safe from the larger fish and predators.
Sometimes Porcelain crabs and clown fish will fight over an anemone, and the clownfish will come out as the winner. Porcelain Crabs often do best when they are kept in a pair.

Their color is really bright like reds, purples, pinks, greens, white oranges and yellow. They have these filter feeder so their colors made without photosynthetic. This coral doesn’t have any dendrophilia corals and doesn’t have any zooxanthellae.
They will depend on the amounts of zooplankton to keep alive. To live they need the perfect water movement.This creature is aposymbiotic Nephtheids. If you never know what was that? They eat only at night, filter deeseer, and non-photosynthetic. They will catch microscopic foods particles from the water column and absorb the dissolved organic matter.
The Dendronephthya genus is the easiest species to identify in the family of Nephtheidae family because of their bright colors. But, they have a good another characteristic as well. It can grow in a fascicular fashion of bundles or clumps.

8. Clypeaster Australasiae (sand dollar)
The Sand Dollar Urchin (Clypeaster australasiae) is species that belongs to the echinoderm family Clypeasteridae. It is commonly found in Australia.
A live sand dollar normally has a hairy dark color like black purple. You can still see that outline of almost a flower on their back but underneath side of them, you don’t actually see that opening the same way.

It is considered as cleaner shrimp because they eat parasites and dead tissue from fish as the part of their diet. The species is living across the tropics. Normally living in the depths of 5-40 meters from the surface. They commonly be found in the natural part of the coral reef ecosystem.
