Bugs that have a snail-like shell?
I'm asking for the impossible as I don't have a picture of the critter I found due to the lack of a macro lens, but I'm going to try anyway.
My tank is planted and is well kept. I vacuum, do water changes once every 5-7 days, do not overfeed, water parameters are good, ect...
Yesterday, I along with my tetras spotted something climbing up a wall of their tank. I do have 3 nerites, but whatever this thing was, it was about the size of a head of a pencil and when not on the glass moved really fast. It had the shell of a snail, but in my experience with snails, none of them zip around the tank.
The shell was dark in color and if I had to describe the shape, it was almost like a Malaysian Trumpet snail shell, but not as pointy. I tried googling different bugs that can appear in a planted tank and the only thing that came close was water fleas, but the color was wrong. The way this thing move was similar though although it didn't 'hop'.
Once I was able to pick it out of the tank, whatever it was, it stuck to my hand. I haven't seen anymore and I've been checking for these things with lights on and off.
Can anybody take a guess what this thing was?
