Tiny black...

[ShesEasy]

Or brown or what ever colour it is, bug

I've got a tiny little criter on my one acro it's smaller then a copepod...it's minute but it moves and it's on my acro. I've only seen one no more then.

Any ideas

Oh and it's there after I dipped it in Coral RX and fresh water but it's back on there

Sorry this won't be very helpful, some people consider them to be similar to red bugs, and some people believe they are a natural clean up crew for dying SPS tissue/skeleton. This was based on a quick Google search for you, hopefully someone with actual experience will chime in.

Tbh that makes sense...I've only seen this bug on the white of the STN...concern was he might be causing the STN.

I have little black bugs on my empty frag plugs, don't appear to cause issues
