Escaping Nerite Snail!
So I posted a photo of the top of my 5 gallon tank. I have a betta, 2 ghost shrimp, and a nerite snail. I'm wondering why my snail keeps escaping. Is there something wrong with my tank or the water? There are wide open spaces the little guy can climb out of so I've had to put cling wrap over the top dvd he STILL got out. That's twice he's escaped and luckily he's still alive. Does anyone have any idea why he's trying to escape? Or is that just a nerite snail thing? Any suggestions on how to fix my tank so he can't get out? The white thing on top hold the filter and pump and the water cascades down into a waterfall into the tank. The temp is around 77-78 degrees F. The water parameters are as follows: Nitrate-20 (which is usually 0). Nitrite-0. Hardness-150. Chlorine-0. Alkalinity-150. pH-7.5. HELP!
