My tank has been up and running for a few months now but today was the first time I noticed some hitchhikers. Maybe I'm super un-observant...
Anyway, I'm pretty sure the first is a pineapple sponge and the second is a feather duster, but I just want to confirm. Also, the third pic is of some zoas I have, I just noticed a section of them with a brown blob. Is this the brown jelly disease I have read about (not the GHA, the blob to the left of that)? Sorry if picture is unclear.
