Lawnmower Blenny is Too Skinny. Help Him......

I think you will find a lot of people here that had a LMB - including myself - where it was doing fine then after a few months or a year they start to get skinny and unfortunately pass away.  Try some algae sheets mine did eat mysis but it didn't help - good luck]

 

Try feeding nori or green cubes. If that doesn't work, try finding someone with an algae scrubber who can donate some hair algae weekly to feeding your lawnmower blenny. Then, build your own algae scrubber and feed your other fish heavily enough to make your own hair algae to feed him weekly. Other than that - I got nothin'

LMB's are one of those "Better left in the ocean" kinda fish...

 

You could definitely sustain him though if you had your own algae scrubber... Just a thought.

I agree snakester
 

 

So far mine's been doing good for a year and a half (knock on wood).  No algae in my tank either.  I've always supplemented with sheets, emerald entree, frozen meaty foods (rod's food)  and pellets (which he loves).

Get some type of frozen meaty foods (rod's food) mixed with veg

A sweet pea????

I'm of the train if thought that these guys are not really suited for the home aquarium as well. Sure, a few have luck, but the greater majority do not. Offer some algae sheets. If he doesn't take to the sheets, try holding them in the water and breaking them up in between your fingers (it will look like flake food). It helps to turn the return pumps off for a bit while doing this. Even if he doesn't go for the flakes, as they settle on rocks around the tank, he may start scraping them off. The hope is that he'll start to make the connection that these flakes are food and will start to take them more willingly from the water column when you feed. This has helped my algae blennies (black combtooth and tailspot) significantly over the years.

Also try some veggie/meat mixes such as Emerald Entree and Angel and Butterfly frozen blends. PE Mysis can also help to fatten him up if he will take meaty foods, as well as small grated chunks of raw wild salmon. Add vitamins such as Selcon or VitaChem to the food as well for added nutrition.

I recently just lost a LMB that got way too skinny very quickly. Unfortunately, if he is super skinny he will most likely just give and not eat anymore. I am from the train of thought that these guys are best suited for the ocean.

Sorry for your loss! 

 

How big is your tank? What else do you have in the tank as far as fish and inverts?

 

Part of the issue with Lawnmower Blennies is that they are really good at cleaning the rocks, almost too good, and once it's gone, they starve.

Sorry about your loss. I've lost 3 LM blennies, so after my third one I thought "enough is enough"

Saddest thing is that one of them was named Lenny, too.

 

A pack of snails makes for a great algae- destroying crew!
