Here is my lawnmower blenny (Salarias fasciatus). One of my favorite fish in my tank because he is so hilarious to watch. He's a very curious fish that loves to watch me watching him.. and his puzzled-confused-facinated facial expression is just hilarious to see. This is his first time on camera and his first time seeing a camera so he was a bit nervous. He typically doesn't scoot around like a scooter blenny like he did in the beginning.. but he's quick to get over his camera-shyness. Love it when he gulps because he has such a suspicious look on his face like he's upto no good.. He's always munching away at the rocks even though i don't have hair algae.. but i guess he's munching away at microalgae that develops daily because he's always so stuffed. He loves when I add marine algae on an algae clip and he often goes to the area where I place the clips and wonders.. "..heyyy! where's the algae..!!!"

Overall great fish with an amazing personality! I've head some people have trouble keeping lawnmower blennies because of their diet, but I don't really do much to feed him and he's been with me for almost a year now so that's great. Adding algae strips isn't necessary either and he'll survive just fine but it's always a great treat. He gets along great with the other tankmates especially the scooter blenny (dragonet). I used to have a four-stripe damselfish who was very territorial and hated the lawnmower but i got rid of him and now he's so happy!

If only it were possible to add another blenny to give him a friend I would get a starry-eyed blenny but they often don't get along and it's best to have one per tank.

  • I tried keeping a lawnmower blenny in my tank, but then , it died. :( Then, I got a second one and that died too. I have plenty of algae in my tank. I don't know what went wrong. The surprising thing is that I got a starfish and that is surviving! And they are very sensitive. I wish I still had one. He was very helpful with removing algae and he was also very cute. Any suggestions with what I am doing wrong?

  • @Squidwardedits are you acclimating properly? my blenny adjusted very well to my tank AFTER i removed a 4-striped damsel that bugged the crap out of him. it confined him to one corner of the tank, he got really skinny and almost died so make sure your other fish aren't harassing him. also i read these blennies consume mass amounts of algae when young, but as they mature they don't like algae anymore and often starve. best to get a small one.

  • i just got a lawnmower for my exsessive battle with algae and hes doing work how many gallons is urs in thanks and love the blenny

  • @TheSharkchum my tank is a 65 gallon + sump + refugium. lawnmower blenny is my favorite fish; always so funny and interesting to look at and works very hard to keep the tank clean. they are a naturally curious fish, so he'll provide you with hours of amusement for sure.

  • rofl best fishtank ever.

  • Love the annotations!

  • @Goingpostal1000 Yes Postal is correct. Thank you for your addition as I haven't been too up to date with Youtube in quite some time. Acclimation is important for ALL saltwater fish. This ensures they get off to a good start when being introduced to their new environment. However in my experience, if you notice any territorial or bullying type disputes then you may have to do something about that. Usually switching the rocks around can work to create a foreign environment for territorial fish.

  • @Squidwardedits Floating them in a bag isn't properly acclimating a salt water fish. You NEED to do a slow drip acclimation. If you go to live aquaria they have acclimating instructions. Bascily you pour in a little tank water like every 5 minutes for about 40 minutes. Pour half the water down the drain and do it again. Then put the fish in your tank. Not doing this is causing insane amount of damage to the fish and inverts cellular structure and gills. Please do some reading.

  • lol you have a funny aquarium to watch

  • This video has convinced me to geta lawnmower blenny.

  • @doRYEmon I floated the bag for like 20-30 minutes. Also, I had a damsel in there. I knew he was causing the problem. Then, I took him out and got a clownfish. I put an other one in. He died too! There was lots of leftover food in the tank though.
