My female Guppy has just disappeared. She is not in the filter not in the plants. I do not know where she went at all. I am thinking about getting another Mystery snail though.
Did you check on the floor? Cause she might have jumped. Also, did you check under everything? Even it you dont think it is somewhere but you havent checked, then check becasue fish always seem to find themselves in weird predicuments. Good luck!
Your apple snail. I'm unsure how large yours is, but i had one once that was about 2 inches in diameter that ate an entire dead betta fish. I imagine even a smaller one could make a dead guppy disappear pretty quick.
