sphaeromatid

Hi everyone, I was just looking in my tank with a flashlight when I saw a couple of unknown isopods crawling around my Zoanthid coral, these isopods seemed to be eating away at the fragplug. I went to google to see if they were harmful since i’ve never seen them before and I only came across...

Hey guys, Can you please help me ID? I have a picotank with sexyrimp and ricordea s and just found this guy :) So... what and who is this guy? Please help me :) The video mostly includes its but (i think) you also see him pooping at the end Thanks!
