    Hi all

    i have this white stuff that looks like a spiders nest growing on my substrate.

    i havent noticed it before and i am generally quite observant of things in my tank.

    i cant find anything on the net, so if someone knows, pls help me id it and the consequences thereof.

    my stock: regal tang, yellow tang, cleaner wrasse, 2 black clowns, jumping bean, diamond back goby. a bunch of pyramid snails, 2 mini electric blue hermits, (tho one has gone mia)

    the red pellets are food. usually there is none left because the tangs eat them all.

    its about a 4cm long and an odd shape.

    i'm gonna add the pics as the orig size, maybe that'll help.

    it really looks like a spiders egg sack, with the little dimples and an airy web like appearance.

    could a sponge develop on the substrate and in such a short period of time?

    That can also be "die-off" from something that crawled in there and died.... I have seen this "film of bacteria" cover decaying flesh in the marine tanks before. I am not too sure that this is a sponge, as my system had thousands of sponges - I have never seen a sponge that look like this. Also - sponges prefer darkness.

    looking at the build up of food under that rock i guess its a place where there is little to no flow and "things" end up there so i agree with Jacques some thing is dead there

    i agree with jacques, can you remove it, or touch it? how does it feel?

    I got this when I started my first tank - spider like webs over all the live rock (uncured). I guessed it was some type of fungus growing on die-off but never got confirmation
