What is the cheapest kind of fish to buy as a pet?

It's impossible to say definitively which fish is the absolute cheapest to buy as a pet. Here's why:

* Cost Varies by Location: Fish prices can fluctuate greatly based on your geographical location, availability, and local pet stores.

* Cost Includes More than Just the Fish: You need to consider the cost of the tank, filter, heater, decorations, food, and other supplies.

* "Cheap" Doesn't Mean "Easy": Some inexpensive fish can be surprisingly challenging to keep, requiring specific water conditions or a lot of care.

However, here are some fish that are generally considered affordable:

* Goldfish: These are a classic choice, but keep in mind they grow large and require a big tank.

* Guppies: Colorful, hardy, and relatively inexpensive, they are great for beginners.

* White Cloud Mountain Minnows: These cold-water fish are very adaptable and don't require a heater.

* Zebra Danios: These lively fish are active and easy to care for.

* Platy: Peaceful, colorful, and easy to breed.

Before you choose a fish, do your research:

* Tank Size: Make sure you have enough space for the fish to grow and thrive.

* Water Conditions: Learn about the water temperature, pH, and other parameters that your chosen fish needs.

* Diet: Understand what they eat and how often they need to be fed.

* Lifespan: Be prepared for the long-term commitment involved in keeping a fish as a pet.

Remember, the cheapest fish might not be the best choice for you. Consider your budget, your experience level, and the needs of the fish before making a decision.
