i just noticed this in my 40gb and have no idea what it is
its a gelatinous bubble ive seen something similar to this on a feather duster before but it looks different and i dont see a duster
Looks like a snot bubble
sometimes I find bubble algae that has not been exposed to light that looks similar to this - no coloration.
i think i found out what it was, i think its a slime coat thing from my 6 line wrasse
That's possible. Did it wave in the current?
yes it did
