Suicidal trochus

[kirstyflash]

We have a huge trochus named Mammoth. He is a great addition to our clean up crew but he has some quirks.
-He is a bulldozer. Nothing graceful about him. He knocks over anything that isn’t glued down and moves the corals sitting on the sand bed.
-He travels up to the top of the glass, leans back and squirts water all over the outside of the tank and the floor (yes he does actually squirt the water, found out the hard way when I went to push him down and he squirted me)
-lastly, on two occasions he has gone walk about outside the tank. One time we found him half way down the outside and this morning I found him on the floor on his back (freaked out, threw him back in the water and made sure he was right way up...he woke up around 3 hours later and mosied around like nothing happened.)
I know his size is why he knocks things over. I’m more concerned/confused about the squirting and the travelling thing. I know fish have a tendency to go carpet diving and nassarius do some travelling too...but what is going thru his little mushy brain??

Mine is the total opposite. Just sits there and stares at me. Doesn't move. Doesn't shift sand. Might as well be an empty she'll at this point. I think it traveled only 3in last month.
Mushy brains indeed.

They are so pretty with their cone shells but dang they are dumb as dog ****

Sometimes slow snails is an indication that the magnesium is high. I would check that for @icejam. Or it could just be a really lazy one.

Trochus are usually in high current, and even tidepool like areas. So they naturally want to pop out of your tank aka tidepool to see what else there is. I've noticed that if they can get back to water within 12 hours, they'll be good. Anything after that is iffy. I've lost most of my trochus because I didn't catch them outside the tank in time.

Thanks. He’s a bugger. We put the top back on to stop him now. He killed all his beautiful coralline last time so all the algae he has just regrown is going to die off now.

I don't have magnesium test but he's the only one like that. The other 3 are all over the place, constantly active, just going about their snaily businesses.
The lazy one is much larger than the rest and has a light green shell unlike the others.
I also don't have any issues with nassa snails which I think are the fastest snails on a planet - especially when I feed shrimp - their on it like a horde of zombies.

I do feed my lazy trochus algae wafers once a week as I am afraid it's not getting enough food and I have to put it right next to it otherwise it will not eat.
Maybe it broke a leg?

Broken legs are normal for old trochus I've heard

Yeah my tank has had pretty high magnesium (Aquaforest Reef Salt mixes at about 1800ppm, it's ridiculous). My nassarius never had issues, but I noticed trochus, turbos, and cerith being way more sluggish. When I slowly got the magnesium down, all my snails started moving way faster. Not sure if it's a coincidence (might have just taken as long for them to acclimate to the tank as it did to get the mag down), but people have reported that mg does indeed do this.

but if your other trochus are good, most likely just an old lazy broken legged trochus.
