The Ultimate Guide to Choosing the Perfect Hiding Spot for Your Fish or Reptiles

If you’ve ever watched your fish dart into a cave or your reptile retreat into a tunnel, you’ve seen instinct in action. Hiding spots aren’t just decorative — they’re a survival tool. In the wild, fish, shrimp, amphibians, and reptiles rely on shelters to rest, reduce stress, escape predators, and even mark their territory.

In captivity, the right hide can make all the difference to their health and behaviour. In this guide, we’ll walk you through why hides matter, how to choose the right one, and exactly where to place them for maximum benefit — so your pets can thrive, not just survive.

Why Hiding Spots Are Essential

A good hiding spot provides:

  • Stress relief — reduces constant exposure, which helps prevent illness and colour fading.

  • Aggression control — breaks line-of-sight to stop fights before they start.

  • Natural behaviour — encourages burrowing, resting, and territorial displays.

  • Security for molting or shedding — a safe place during vulnerable phases.

How Many Hides Do You Need?

The rule of thumb: One hide per animal — plus an extra.
This prevents competition and ensures everyone has a safe retreat. Overcrowded tanks or enclosures without enough hides can cause stress, injury, and even death.

Choosing the Right Size and Style

For Small Tanks or Nano Setups

Opt for compact hides that won’t dominate the space. Tight entry points keep out larger tankmates while giving smaller species peace.

For Larger Tanks or Multiple Pets

Go for multi-entry or long tunnel designs. These allow multiple pets to use the hide at once and create more “escape routes” to avoid confrontation.

Where to Place Your Hides

  • Aquariums — Place near plants or hardscape to mimic natural cover. Avoid blocking main swimming lanes.

  • Terrariums — Create warm and cool hide options so your reptile can regulate temperature.

  • Shrimp Tanks — Keep hides near moss or fine plants to encourage grazing in safety.

Quick Expert Tips

  • Rotate hide locations every few months to keep your pets engaged.

  • Pair caves with live plants for a more natural, secure feel.

  • For shy species, position hides in low-light areas.
