10 Gallon Tank Mystery Snail Fight?

Hi everyone,

I had 4 mystery snails in a 10-gallon tank with 2 ADFs. Two days ago I noticed that one of the larger Mystery Snails (Ivory) was upside down at the bottom of the tank with half his body sticking out. I thought he was dead, but when I picked him up he shrunk back into his shell. I put him in a different tank and checked the water conditions which were all optimal. I did a 25% water change just in case. After a couple of hours I noticed that the mystery snail had started moving around the other tank I had put him in, but he would never go back into his shell fully and any time he went to the floor of the tank, he would lay sideways. I left him there with some food overnight and the next morning he looked great, had eaten the food, and was moving around the tank. I put him back into the larger tank. He continued to move around and I didn't see any issues. However, that evening I came in and the other large snail (Golden) was on top of him and it looked like he was trying to pull his shell back (picture attached). I separated them and put the ivory one back in the separate tank, but the next day he was dead. Do mystery snails fight? Should I watch the Golden snail in case he tries the same with the other snails?

 

It was probably mating

 

I know they are both male and that they sometimes they still try to mate with each other which I had seen them do before, but never this aggressive.

 

Nevermind, lol..

 

Male mystery snails will often try to mate with each other lol. Snails only have 2 purposes in life- to eat and to mate. I don't even think that they can tell each other apart lol. Your snail sounds healthy to me quite honestly, it was probably just tired from trying to get busy all afternoon sometimes they do weird things as well. Funny little critters with unique personalities
