Mucus-like Webbing on Rock - Question on Flow

[Michael Hull]

Trying to understand what might be in a few different spots on my rock. I've got a healthy ecosystem, but noticed in a few areas on the rock that there is a spider web like/mucus like substance waving in the current. Its not vermetid snails, I know what they look like, and its not a sponge. Honestly looks like mucus thats just sitting there and floating around. It can be sucked up with a turkey baster, but I've noticed a few little patches of it around the tank.

Also, I've got the Red Sea Max tank that has three internal powerheads on the back, but they can't be angled down enough to hit the back side of my rock structure... wondering if I should mount a powerhead lower to push water through the rocks towards the front of the tank... thoughts? Here's a full tank shot, you can see those powerhead up on the back. But the back of the rocks down low doesn't get much flow.. and I have that Nero powerhead on left raised up higher now to provide flow to the top half of the back of the rocks... but nothing keeps much of a current down low on sand in back.

Could be mucus cocoon from your wrasses if you have any. They form one when they sleep.

Wow!!! Yes, I have two wrasses! A melanarus and a red fairy. That's definitely what it is, I looked it up and its spot on! Thank you!!!

Yea, it's from your red fairy then. Melanarus sleeps in sandbed. Red Fairy will create cocoon from its mucus and sleep in the rocks.
