Aggressive Lawnmower Blenny

[InCodWeTrust]

I added a Rusty Angelfish to my tank but my normally timid Lawnmower Blenny doesn’t seem to enjoy the new addition. Any thoughts on reducing the aggression towards the angelfish? Also feel free to post other aggressive or strange Lawnmower Blenny stories.

Plant some nori on a spot in the tank. The blenny will have to choose between being an AH or eating salad :)

Do you know a way to entice him into eating the nori? I tried feeding him nori before but he never takes a bite.

Try some garlic extract :) Also, put it right in front of his favorite bedding spot.

i had a similar situation except the blenny was introduced after but it would chase my clowns out of their leather and the blenny would perch in it and anytime my clowns got close the blenny would chase them away. it lasted probably less then a week until i think it just forgot and the clowns were able to stay in their leather again.

Thanks! Will give it a shot tomorrow!

Blennies will sometimes attack fish that they perceive as competitors for algae on rocks.
So, tangs, angels, foxfaces, etc are all fair game.
I've got a blenny that has sucker punched all of the above.
One hit and he then flees before they can react.
Leaves a nice mouth-shaped scrape mark on their sides.
I've never seen a blenny take to nori. And certainly not before all the other herbivores devour it.

I am having the same issue. Added an algae blenny and never had problems before. He is terrorizing my Yellow Watchman Goby, my Flame Hawkfish, and my beautiful golden Midas Blenny. If I can catch his butt, he's got to go!

My gigantic lawnmower killed my tang, 2 clown fish, my mandarin and my Aussie stripy. I hate him!

Rusty Angels are beautiful, and hardy. Nice choice-- so many people overlook them.

I also have a very large Lawnmower Blenny, and he is very peaceful and chased by my tangs and occasionally my Emperor Angel. Mine will only eat Algae but would take nori as long as it was rubber banded flat to a piece of PVC. Make sure he has a place like under a Rock or between.
