What are these snails doing? I got out of bed because I thought I heard a noise and everything is fine but these two snails are up to something. The black one is wrapped around the gold one and the gold one looks like he keeps throwing his back around trying to throw the black one off.
I never found any clutches and eventually separated them. The black one was eating far more than the other and the gold wasn't getting enough food I think. The black one climbed on the gold one several times and every time the gold one would shake it's shell around like it wanted to other off.
Definitely mating! If you want to put them back together you can place food in two different places in the tank and put one snail on each then once they leave the food, put one piece of food in a central area. If you don't want up to 200 baby snails you can simply remove the egg clutches after a day or so and put them in the freezer to kill them. I'm not sure what color the two would produce but snails get their color from both the shells and the foot (body). A gold snail has a white foot and a gold shell. A black snail has a purple/black shell with a black foot. A blue has a white/yellowish shell and a black foot. An ivory aka white snail has a white foot and a white shell. A magenta snail has a white foot and a purple shell. A purple snail has a black foot and a purple shell. I hope this helps you understand better.
Oh yeah, since they mated I think you can expect an egg clutch even though they are separated. I believe female mystery snails can hold sperm for up to a year but don't quote me on that. I'm here if you need any further help.
