Pest Id

A fun thing to spot when I get home from work. 🙂😅 time to get a crab I guess

Eating algea every time

Short video of the random marks / tracks that keep showing up on my rock

Anyone know what this white looking spongey thing is? Came with the rock

Trying to id this stuff growing over my rock

Its balck / brown in color blows off easily with a feeding tub and sucks up easily during water changes

Can clean it off the rocks today and 2 days later its back ai and local reef pages ( in new zealand ) havent been much help any ideas

#help I do not know that is this. It' form is thin and not soft, little hard. Could someone help me to identify this thing?

First thought was a snail, but now I’m not sure.

Anyone know what these are ?

Is this an asterina starfish????

Are we thinking dead hermit or malt?

I found a very well camouflage hitch hiker in my xenia!

Apparently they are called xenia crabs (not gonna lie I really did not saw it until i really took a closer look to inspect my xenia for damges and noticed some stalks that does'nt have some fingers and was like whoa why is that stalk moving sideways!!)

They have a very cool symbiotic relationship on a xenia, they eat xenia while they also protect xenia!

Will this help me control xenia's weed-like nature that spread quickly or will i need to find him a friend?

Look at 2nd pic and have fun finding him 🤣

I found this well camouflage crab in my xenia, what is this crab and is this safe for my frogfish?
