hey all..i saw my blenny trying to bite my ocellaris clown..and a few days ago, my smaller ocellaris clown died and there is a bite mark at the stomach...
in the tank, there are only 1 lawnmower blenny,1 ocellaris clown, 4 b/g chromi and 1 bicolor dottyback

As weird as this sounds...some are aggressive. I took in a cowfish that had his whole tummy scarred up by an LMB. :scared:

I've had a LMB for almost 2 years and he is not even remotely aggressive! In fact he's the "real clown" and show off of the tank!

That is how mine is..unfortunately some fish don't read the manual on how they are supposed to act.

One of my damsels has learned not to pick on my bicolor blenny. The damsel takes off anytime the blenny come near. I think the damsel asked for because I have never seen the blenny being mean to anything else.

Trade him in on a new modle.
I had some peppermint shrimp that thought my LTA was a snack... :mad: Well they went back to my LFS and then bought some different ones.
I personally think it is all about when you add things in your tank.
The shrimp were first and became very comfortable, can not blame them.

my lmb is aggressive towards my diamond goby. he'll perch on the rocks and wait until the diamond goby comes out to sift the sand n will dive bomb him. i added a sebae clown before and he went after him too. the clown ended up dying 4 days later even tho he ate fine and had no signs of disease

id get rid of the lmb but, he does such a great job on the algae on the glass. he just gets in his moods sometimes and feels like bullying

if you have a qt tank or sump you could take him out for a week or so and then re-acclimate him to your main tank "in the dark for a couple hrs" then the tables would be turned and the other fish would be more dominant

I believe you will see aggression sometimes between tangs especially..and blennies as they compete for the same food in the tank~ the algae. Usually it's the blenny getting the beating, but it can go the other way. Overstocking and aggression is something I have learned as a hard lesson. Working at an LFS it is tough..I see so many beautiful and cool fish I want one of each!
I just recently tore apart my 75 gal to remove five small-med fish. There were just too many...that the fish would bump into each other at every corner. Now the tank is much more peaceful..and I am starting to see small fish and the inverts come out more..as they realize the number of fish has been drastically reduced. It's one thing to overstock when you are new in the hobby...it's another to do it when you know better. :thinking:

If you remove the blenny it might also help to rearrange your tank. When it returns, it will feel like the new kid on the block and can't won't recognize his "territory". If you change it so that it's no longer his turf he may lose his aggression.

That is a good point and can hold true for the majority of commonly kept species...I've never seen aggression issues with lawnmowers but I suppose it is possible.

My LMB has been cranky too i've seen him go after my clowns a few times. and i've also seen him pick up my hermits and toss them all over the place and found at least four of them half eaten laying on the sandbed. but the funny thing is he and my BI COLOR angel share the same cave and not once have i seen those two fight hmm wierd.
