I caught my octo out tonight and when he saw me he jetted off and let out a really small thin thing of ink. It seemed to dissipate instantly. I have a protein skimmer in the system for this tank (30 gallon). He is a really tiny guy. I put a pic for reference..Should I worry about it and change the water or will a very small amount be ok until my next change in a few days?
