KeepersNook Expert care guides for every keeper

Care guides, not care myths

Know what the animal needs before you bring it home.

Housing sizes, water parameters, safe foods, and tank mates, written against primary sources by keepers who have made the mistakes already.

Keeping fish, poultry, reptiles, birds and small mammals

Every guide cites its sources

Journals, university extension services, and veterinary bodies, listed at the foot of the page.

Real measurements

Enclosure sizes in inches and litres, temperatures in degrees, not "a decent sized tank".

Feeding safety checked twice

Anything a reader might feed an animal is verified against a primary source before it ships.

One named editor

Every page carries a byline and a contact address. Corrections reach a person.

Before you buy

How hard is it to keep?

Care level describes what the animal demands of you, not how good the animal is. An expert species is not a better pet, it is a worse first pet.

Beginner

Forgiving of small mistakes. Recovers from a missed water change or a late feed.

Standard equipment, wide tolerance for parameter swings, easy to source food.

Intermediate

Needs a routine that holds. Mistakes show up within days rather than weeks.

Specific parameters to hold, some specialist equipment, a real weekly schedule.

Advanced

Narrow tolerances. Assumes you already keep something at the level below well.

Tight parameter control, dedicated equipment budget, a vet found before you need one.

Expert

Unforgiving. A single lapse in heat, humidity, or water quality kills the animal.

Continuous monitoring, backup equipment, specialist vet access, years of prior keeping.

How we research

Sources first, opinions second

Guidance is built from peer-reviewed work, university extension material, and veterinary bodies, in that order. Where the evidence is thin we say so instead of filling the gap with confidence.

New to keeping

Read these before you buy anything

Three questions decide whether an animal works in your home: how much space it truly needs, what it costs to run each month, and what it can live with.

Open the beginner hub

  • Minimum enclosure sizes that are honest, not the pet-shop number
  • Running costs: heat, light, filtration, bedding, feed
  • What actually cohabits, and what only cohabits until it does not
  • The early warning signs worth knowing on day one
