Hi have one question to ask. I have cycle my tank for one week and I found some red staff on my live rock. Can anyone recognise it and is it harmful? View attachment 4046894

Looks like some type of macroalgae. Where did you get the rock?

The growth is good in my opinion. It looks live. Filled with lots of good bacteria. There could be hitchhikers though.
