Preventing Escape

by Jennifer Macke

 

Escape is one of the leading causes of death for captive newts and salamanders. Unfortunately, most people don't learn this until they have lost at least one animal this way.

There are several things you can do to reduce this risk.

  • Always keep lids closed.
  • Engineer tank lids to make escape impossible.
  • Never assume that a newt or salamander "couldn't possibly". These animals are Houdini-like in their ability to find a way out! Even large caudates (tiger salamanders and 10-inch ribbed newts, for example) have been known to climb out.

The photos below show specific things that you should do (or avoid) when designing a tank lid for a newt or salamander.

Run tubing through holes just barely big enough.

Don't run tubing or cords under a screen lid - not even at the corner. This creates a large enough gap under the lid to allow small newts to escape. This method is OK for large newts.

Large tubing for canister filters can be put through holes cut in the screen.

Don't leave a hole like this open, as newts can climb the cord, like a monkey up a rope!

Seal gaps with electrical tape. (Note that tape may not stick well to a screen lid. Foam, as shown below, is better.)

Seal small gaps with soft foam, wedged firmly into place.

Gaps around tubing can also be sealed by glueing pieces of plastic into place.

Do make homemade screen tops that fit flat against the entire top edge of the tank.

Electrical cords can sometimes be accommodated by making a carefully-sized slot.

For larger newts, a wide rim is enough to prevent escape. The standard rim on a standard manufactured tank is NOT enough to prevent climbing out.

A wide rim, as shown above, is worthless if cords or tubes are present.

Large cut-outs in hoods can be covered with window screen material glued in place.

Plastic tubs should have secure, tight-fitting lids. To improve ventilation, cut small holes.

In an emergency (larvae near metamorphosis and no tank available), panty hose can be used to cover a tub.

In this unusual example, a cat litter box was used as a temporary tank. Duct tape was used to create a wide rim to prevent escape.
