Hi!!

It has been about 4 weeks since my Fish Tank has gone Fishless, due to the ICH issue I had :cry: .. Lost my first Saltwater fish :(

Now.. I have decided after 4 weeks of waiting.. to grab a Damsel...

However!! Here is my Dilemma !!

I have Hard WHITE particles stuck on the back of my NANO cube.. they aren't very big.. (about the size 2 grains of sand)..
I tried to scrape it off with my finger.. but everytime i scrape it off, it's like trying to scrape hard gum off concrete... I counted them all and there is about 100...

Specs

Inhabitants:
3x Red leg Hermits
2x Cerith Snails
1x Peppermint Shrimp

All my Water levels are stable (0 - 0 - 0 - 8.1).. and so is alk and sp. gr. (red zone)

I forgot to add my actual question Lol... Are these WHITE particles on the back of my nano cube ICH ? ICH waiting to devour another one of my fish? or Am I just paranoid ?

Those are normal and common in my tanks. You should be just fine. Did you treat your water with medicine while you had the ich issue?

[Sefu]

no i didn't

Those I believe are oysters, but I am sure someone else might have a better name for them.

I would say spirorbids worms... are they small & spiral shaped?? If you look really, really close, you should be able to see the crown of the worm at the tube opening.

Here's a picture... not mine but a great shot.

I second the spiorbids. They are harmless little filter feeders, commonly found in home aquaria.

Yup those are the culprits.. Thanks guys!!!
