I have a ramshorn and 2 apples in a 10 gallon guppy tank. that ramshorn just laid a huge amount of eggs...my question is, do they crossbreed? is a ramshorn a-sexual? It was by itself in a 30 gallon tank for about 6 months before ever seeeing another snail. it goes in the gupp tank and in 2 weeks its layin eggs
