Spanish Ribbed Newt Missing

[cpc91]

I just bought a spanish ribbed newt yesterday. The tank is fully cycled, 100% covered in plants, and contains several small fish which are almost a year old. PH is buffered at 6.0. I got home from work today and went to check on it and it is no where to be found. I pat down the entire tank with my hands, checked the floors, couches, basically the entire floor to no avail. I have no idea what could have happened to it. The guy at the store told me I didn't need a lid for this species. I expected to at least find a decaying carcass in the tank or a shriveled up body outside of it but nothing. He definitely didn't get sucked up by the cannister filter because there is a tip on the end. Do these guys burrow? Could I just be blind? I spent two hours and have found nothing, but left a wet paper towel in case he comes back.

All newts climb and the most likely time is when they are new and freaking out. Search the corners low down and under things outside the tank. He had all day to find a spot so he can get pretty far.

A full grown adult ribbed newt won't climb out. A juvenile ribbed newt can crawl out.
