Thanks guys, will try it out. Yes, it been exposed to air. Never know this sponge need special care, it looks easy to keep, should have done some research earlier.

Got a Blue Tang but he don't eat. This little ball is hairy and is like a yellow rambutan.

Hi Guys, Anyone know what is happening to this Sponge, it got a layer of something that look like wax over it. Is it dying ? Thanks.

Sure it move, is it harmful ?

Yap, it can move about.

Sorry, here is a smaller picture.

Hi Guys, Anyone kown what is this small yellow thing on my button? it can move. Is it harmful or friendly ? Thanks

I just found out the cause of the problem. Shoelevy was right, is the air bubbles. Although my pump is fully submerged in water, the water flow from my 2nd compartment of the sum create some air bubbles near the return pump inlet hence causing the white particles which is actually very tiny air bubbles. Thanks guy.

I have the same problem with my Naso too, not eating since I bought it a week ago.

Nope, pump fully submerged under water. The white particles are not air bubbles, is like dust particles. Wander if it got anything to do with tap water that I top up.

My return and internal pump sometime blow out white particles, now my tank is full of white tiny particles, anyone know what isit ?

Just brushed my liverock and change my water, tank crash when I was out of town. Saw alot of dead baby crab, might be the culprits. Will monitor condition, thks

NH3/4 = 0 NO2 = 0 NO3 = <25 PH = 8

My live is eroding and the holes are getting bigger, alot of dust in my tank, anyone know what is going on in my tank ?

That means no fish, no parasite ?
