LMB died - why?

I turned my lights on Monday morning and my LMB was laying on its side on the sand, still breathing but he was looking weak. Over the last week or so he has been hiding in an internal cave in the rock. I did have to move the rock the other day and he came out and I am worried it may be related to the stress of that?

He also looked very thin recently but I had seen him eating, though not as much in the last few days. Before this he would look a bit thin in the mornings but then quite plump by the evening so I thought that may just be the way he looked and hadn't been paying a huge amount of attention to his behaviour other than to make sure I could spot him in the tank, as he liked to find lots of different crevices and holes to hide in with a few select favourites.

I rushed to my LFS as fast as I could because I thought he may need more food in an effort to get some more LMB-specific foods and had my wife keeping an eye on him. She said he started doing summersaults and then resting again, landing on his back and then shortly before he died she said his head swelled up really big and his gills were puffing out quite a lot, as well as his eyes bulging with a blue film over them. He had died before I got home unfortunately.

I tested the water as soon as I saw him like that and they came back with 0 ammonia, 0 nitrite and around 2 nitrate, with a SG of 1.024. The LFS also tested a sample and had the same results so there was nothing in the water chemistry to indicate why this might happen. In addition, my mandarin is doing perfectly fine and I would expect him to feel the effects of poor water first, as is my cleaner shrimp.

Does anyone have any ideas?

The only positive I feel I can take from this is that he left the rock and he died in view, so I was able to remove the fish (well, I had my wife do it as I hadn't returned yet) before it started to release ammonia into the tank.
 
Was he having problems staying balanced, or upright in the water? Did he seem to bob back and forth in the water, darting down and then bobbing back up? Did it seems like he was rasping at the surface (trying to swallow air?) or did he swim in the current of the powerhead and then drifts back to lay on his side?

From what my wife tells me, while I was on my way to the LFS, he seemed as though his head was too heavy for him, which is why he was doing summersaults. She says he was flipping and flailing about on his head on the sand and writhing.

He didn't move other than breathing while I was testing the water before I left and while he looked a bit more laboured than usual, he always seemed to breathe quite quickly. He just stayed near the front left corner of the tank, previous to this episode he hadn't done anything listed and I wasn't aware of any symptoms for an issue with his swim bladder. Before Monday, he seemed to get around the tank just fine, though as I say he has been hiding in a cave a lot recently so whether this behaviour also happened in there or not I couldn't say. When he came out of the cave while I moved the rock, he seemed fine though and I believe that was on either Saturday or Sunday.

Edit: From what my wife tells me, it sounds like he deteriorated really quickly from just looking weak on the sand and breathing quite quickly to writhing about and then she says his breathing started to slow right down until it finally stopped. He died as I was coming back from the LFS, which is about a 40 minute round trip, so after 30 minutes or so.
 
A Large Mouth Bass is a freshwater fish.. That could certainly be the problem..

In general a fish could die from an infection, old age and numerous other issues and many times the cause just isn't known..

Ha! I was hoping that someone would say what an LMB is - once I got Large Mouth Bass in my head, I couldn't think of anything else.
 
You would be better off with a Starry Blennie if you decide to replace it, they are much more likely to eat frozen, flake and pellet food and have a much better survival record.

yes and they have awesome personalities too..
I've had both.. My starry was a MUCH better fish..
 
oh.. just hit me.. LMB = lawn mower blenny?

It died of starvation.. Case closed..

I saw him eating though. Was it a case of simply not having enough to eat?

Edit: At this moment in time I've decided not to replace it, though thanks for the advice regarding a starry blenny. I will certainly look into it.
 
yes it more than likely died of starvation.. you said yourself it was looking thin..
IMO a "LMB" is best left in the wild.. or in a very mature/established tank with sufficient algae,etc...

That's a shame, thanks everyone for your responses. I hadn't realised it would struggle for food that much, I shan't make that mistake again.

In addition to the starry blenny, are there any other similar fish that would make good additions?
