I have no idea what these are I just noticed a few on my sand so I sucked it. They are very tiny this photo is the best I could do not sure how to upload videos
Others may have other experience with them...... I used to see them occasionally in an old setup years ago..... my clowns uses to pick them off the glass.... they never caused me a problem.
They can irritate more leathers and lps. Their irritation can cause the coral to close up and may starve the coral to death via lack of light. It would be best to nuke them with flatworm exit.
That’s what I’m thinking I only have a few that I can see in researching it now and it’s crazy some of these tanks with hundreds of them. Gonna nuke them before that can happen lol
When you nuke them they can release toxins. That’s why you should have a 10-20% water change ready and a crapload if carbon in a reactor ready to soak up the toxins. Directions are in the box.
