Well I purchases 4 small-medium Nerite snails a while back and ever since I got them they will just stay in the right side back top corner. lol. Some of them will even try to get out. I found 3 of them outside the tank already haha.
I guess they dont like my tank.
Anything I can do to make them stop escaping from my tank?

put them on the rocks

With a wedge of lime, and maybe a squirt of tonic water if you're a wussy.

I do put them on the rocks and then they keep going to that corner lol

same corner huh? they are looking to escape the light, they are nocturnal, that corner receives the least amount of light in your tank I bet. (or reflects the least if there is an opaque overflow they are chilling on. Check up on them in the middle of the night and see what they are up to.

I've followed trails to find nerites under my sofa in the past. I find them out of the water at the beach more often than not.

what beach do you get them at?

Mine do the same thing, they will just randomly go back onto the rock for a while then come back to the water line for a day or two.

They were crawling all on the rocks

ha, i was just kidding you buddy..fishing joke....

they act that way, if you have a rim it shouldnt be a problem, but they tend to fall out if you are rimless. is that the case?

I can share some snails - now, if I was pulling out fancy zoas and magic chalices, I'd have to kill you if I told you.

not sure the status of the chalice market, but I got a zoa spot for you, trade me spots in pms, otherwise they will not be spots for long. shame but the that is the truth...

i like your style sword. pm to be sent...
