Hi guys, I've had some brown stringy/hairy algae growing on my tank walls for a while (ever since my skimmer broke) but it hasn't bothered me too much. I admit I have been feeding a bit more but I will be sure to stop

, but I wanted to ask if a algae blenny would eat this stuff. I used to have one but my tank was not prepared and sadly it died, but I always loved their personality.
and just a question on compatibility, I have a small watchman goby and a yellowhead jawfish in the tank already (40 gallon). I know there is the issue with same body type but I do not think they would meet each other considering the watchman is always with my pistol shrimp in the burrow and my jawfish has his own spot. What do you guys think about if there would be any issues? Thanks you guys
