Planning a New Pet or Habitat?
Start with the type of animal you're keeping. Each section below covers what to expect from that branch of the hobby, what decisions to make before you buy, and where to go for species care, setup guides, and equipment recommendations.
Planning a new animal? The HabitatCraft New Animal Planning Workbook walks you through research, budgeting, habitat planning, and arrival prep before you commit. Or use the free New Animal Setup Checklist → to make sure your habitat is ready before your animal comes home.
Not Sure Where to Start?
Want an aquarium? Start with Freshwater for the broadest range of beginner setups and the most flexible budget range. Go Saltwater if you're specifically interested in marine fish, reef systems, or the challenge of maintaining a more complex ecosystem.
Want a terrestrial animal? Reptiles offer the widest range of species, interaction styles, and keeper experience levels. Amphibians tend to emphasize environmental husbandry and observation over handling. Tarantulas and scorpions suit keepers interested in invertebrates, compact enclosures, and animals that are genuinely fascinating to keep without requiring daily interaction.
Freshwater Aquariums
Freshwater aquariums are one of the most flexible places to start. Setups range from a single Betta in a small planted tank to community aquariums with schooling fish, bottom dwellers, algae grazers, and freshwater shrimp. The equipment is widely available, the livestock is affordable, and the hobby scales as far as you want to take it.
Before choosing a species, consider tank size, your tap-water chemistry, how much maintenance you want to do, and whether you want a single-species or community setup. Beginner-friendly options include Guppies, Bettas, Corydoras, Neon Tetras, and Cherry Shrimp. More specialized shrimp — particularly soft-water Caridina — require tighter parameter control and more deliberate equipment choices.
Our freshwater section covers individual species care guides, complete community-tank builds by tank size, water chemistry guides, equipment recommendations, and setup checklists.

Saltwater Aquariums
Saltwater aquariums require more upfront investment than freshwater — in equipment, in time, and in patience. A saltwater system must be fully cycled before livestock is added, and some species require a substantially more mature system. Water chemistry demands consistent monitoring, and the cost of equipment adds up quickly.
Before starting, consider your budget for equipment (protein skimmer, lighting, live rock, salt mix, and test kits), how much time you can commit to maintenance, and whether you want a fish-only system or a full reef with corals. Beginner-friendly species include Clownfish, Firefish, Royal Gramma, and Tailspot Blenny. More demanding species like Mandarin Dragonets and Blue Tangs require established systems and more experience.
Our saltwater section covers reef fish species guides, community reef builds by tank size, water chemistry and equipment guides, and complete setup checklists.

Reptiles
Reptiles are one of the most diverse groups of animals kept in captivity. The species you choose determines almost everything else: enclosure footprint, heating and UVB requirements, humidity levels, feeding type, and how much daily interaction the animal will tolerate. Getting the species decision right before buying equipment saves significant time and money.
Beginner-friendly options include Leopard Geckos, Corn Snakes, Bearded Dragons, and Ball Pythons — all widely kept and extensively documented, with established captive-care practices. Intermediate species like Boa Constrictors and Chameleons require more deliberate setups. Lifespan is worth factoring in early: many reptiles live 15–30+ years with good care.
Our reptile section covers species care guides for snakes, lizards, and tortoises, along with heating and UVB guides, enclosure sizing, substrate, feeding, and complete setup checklists.

Amphibians
Amphibians are primarily observation animals. Most species tolerate minimal handling, and the appeal is in building and maintaining the right environment — humidity, temperature gradients, water quality, and live plants — and watching the animal thrive in it. For keepers who enjoy the habitat as much as the animal, amphibians are a natural fit.
The most important decision before choosing a species is whether you want a terrestrial, arboreal, or aquatic setup. Pacman Frogs and Fire-Bellied Toads suit different enclosure types than White's Tree Frogs or Axolotls. Amphibians are also generally more sensitive to water quality and chemical exposure than reptiles, so substrate, water source, and supplementation choices matter more from the start.
Our amphibian section covers care guides for frogs, toads, and aquatic salamanders, along with enclosure setup, humidity management, feeding, and equipment recommendations.

Tarantulas
Tarantulas are low-maintenance invertebrates that suit keepers who want an interesting animal without the daily feeding and interaction requirements of reptiles. Most species eat once a week or less, require minimal enclosure space, and are genuinely fascinating to observe — particularly around molting, webbing behavior, and enclosure use.
The key decisions before choosing a species are terrestrial vs. arboreal vs. fossorial (burrowing), and beginner vs. intermediate temperament. Generally slower-moving New World species commonly recommended to beginners include the Mexican Red Knee, Curly Hair, and Chaco Golden Knee. Arboreal species and Old World tarantulas are faster, more defensive, and better suited to keepers with some experience. Molt tracking and enclosure records become important once you're keeping multiple animals or working toward breeding.
Our tarantula section covers species guides, enclosure setup for terrestrial and arboreal species, feeding, molting, sexing, and breeding.

Scorpions
Scorpions are display animals first. Handling is possible with some species but is generally not the point — the appeal is in keeping a genuinely ancient, well-adapted predator in a correctly built enclosure and observing its natural behavior. Most commonly kept species are nocturnal and spend significant time in hides, so enclosure design and substrate depth matter more than they might initially seem.
The most important distinction before choosing a species is tropical forest vs. desert/semi-arid. Emperor Scorpions and Asian Forest Scorpions require high humidity and moisture-retentive substrate. Desert Hairy Scorpions require dry, deep burrowing substrate and appropriate temperatures — a fundamentally different setup. Venom potency varies significantly by species and is worth researching before purchase.
Our scorpion section covers species guides for tropical and desert species, enclosure setup, feeding, molt tracking, and brood development for keepers working toward breeding.

Going Away?
Leaving your reptile, aquarium, amphibian, tarantula, or scorpion with someone else? The HabitatCraft Going Away Care Sheet gives your pet sitter one place to find feeding instructions, daily care, equipment notes, emergency contacts, and the things they should not change while you're gone.
Not Sure What Equipment You Need?
Once you've chosen a branch, each species guide links directly to relevant equipment recommendations. For aquarium and reptile keepers, setup checklists cover everything you need before your animal arrives:
- Freshwater Aquarium Setup Checklist
- Saltwater Aquarium Setup Checklist
- Reptile Setup Checklist
- Amphibian Setup Checklist
For tarantulas and scorpions, start with the species guides above — each guide links to the enclosure, substrate, and other equipment appropriate for that species.
