Hello, Its been 4 moths now

[Massiso]

Well its been 4 months and its been great, there has not been a single day since I got into the hobby that I have not thought of my tank

and I can't wait for the next 4 to come

Here are some old pics and new ones too :












Now can anyone tell me waht is this in the middle of the pics its brown and bubblely I thought maybe it was the mushroom that detached from the rock but I think I found that one today behind a rock, it has 2 openings that look like hole that open up, it first apeared by the mushroom rock but I moved it where you see it now. When I picked it up it shriveld up








The other surprise was 2 brittle stars or maybe feather stars in the rock that my mushrooms came on I saw them often @ first but I don't see them anywhere now could they have been eaten? they were tiny.
