FishCare AI: Aquarium Care Guides, Fish Encyclopedia & Free Aquarium Tools

FishCare AI: your complete fish care and aquarium care guide

FishCare AI is an all-in-one fish care platform built to help aquarium owners keep healthier fish and build better aquariums. From beginner aquarium care and species research to aquarium planning, water quality, feeding, compatibility, fish identification and common fish health problems, FishCare AI brings practical aquarium information and free tools together in one place.

Whether you are caring for your first betta, planning a community tank, researching goldfish care, or trying to understand why a fish is behaving differently, FishCare AI is built to make aquarium keeping easier. Explore the fish encyclopedia, use the free aquarium tools, check fish compatibility, identify a fish from a photo, or browse detailed fish care guides for hundreds of species.

Why use FishCare AI to plan your fish tank?

Good aquarium care starts with understanding what each species actually needs. Different aquarium fish require different tank sizes, temperatures, water parameters, diets, social groups and tank mates. Advice that works for one species may be unsuitable for another. FishCare AI organises that information into practical fish tank resources you can use before and after adding fish to an aquarium.

• Research fish species and their care requirements
• Find recommended tank sizes and water parameters
• Compare fish tank mate compatibility
• Check aquarium water conditions
• Plan fish feeding
• Identify fish from photos
• Explore common fish diseases and symptoms
• Calculate aquarium requirements
• Learn freshwater fish care

Instead of searching across dozens of websites, FishCare AI gives you a central starting point for everyday fish tank and aquarium care.

Fish encyclopedia

Every species has different care requirements. The fish encyclopedia helps aquarium keepers research species before adding them to a tank. Each fish profile covers adult size, minimum tank size, temperature, pH, diet, temperament, social requirements, compatibility, care difficulty and common health concerns.

This matters most when buying juvenile fish. A small fish at the aquarium store may eventually need a far larger tank than expected. Use the encyclopedia to research popular aquarium fish including bettas, guppies, mollies, goldfish, angelfish, discus, corydoras, tetras, gouramis, barbs, loaches and cichlids.

Freshwater fish care

Fish care for beginners begins with a properly sized and cycled aquarium. Before adding fish, make sure the tank has suitable filtration and an established nitrogen cycle, and test ammonia, nitrite, nitrate, temperature and pH regularly.

Requirements vary sharply between species. Betta fish generally prefer warm water and gentle flow. Goldfish produce large amounts of waste and need strong filtration. Discus require warm, stable water, while schooling fish such as many tetras should be kept in appropriate groups. FishCare AI publishes species-specific fish care guides so you can research those differences rather than applying one rule to every aquarium fish.

Free FishCare AI aquarium tools

Fish care often involves calculations that are hard to make from general advice alone, so the aquarium tools here are built around the questions fishkeepers actually ask.

Aquarium size calculator

How big should a fish tank be? The aquarium size calculator estimates an appropriate tank size for the fish you want to keep. Tank size is a core part of a responsible fish tank plan: adult size, activity level, territorial behaviour, group size, waste production and swimming space all matter.

Fish compatibility checker

Choosing compatible tank mates is essential to a stable fish tank. The fish compatibility checker compares species on temperament, adult size, water conditions and temperature range. Use it before introducing new fish to an established aquarium.

Aquarium water parameter checker

Water quality affects almost every aspect of fish health. The water parameter checker helps you read ammonia, nitrite, nitrate, pH, temperature and hardness against safe ranges. If a fish suddenly hides, gasps, refuses food or swims unusually, testing the water should be one of your first steps.

Fish feeding calculator

Correct feeding is another daily part of aquarium care. Overfeeding degrades water quality, and species differ in what they need. The fish feeding calculator gives a practical starting point for how much and how often to feed.

Aquarium planner

Planning before buying fish prevents many common problems. The aquarium planner walks through tank size, stocking, compatibility, equipment and cycling before you build the community.

Fish health resources

Is a fish not eating, hiding, gasping at the surface, swimming sideways or showing white spots? Behaviour gives useful clues, but similar symptoms have many different causes. The fish health library covers common problems, symptoms, likely causes and prevention.

Warning signs worth acting on include loss of appetite, rapid breathing, gasping at the surface, white spots, clamped or torn fins, unusual hiding, faded colour, bloating, buoyancy problems, rubbing against objects and erratic swimming.

Before assuming a specific disease, check the environment. Poor water quality, ammonia or nitrite exposure, wrong temperature, low oxygen, aggression, overcrowding and sudden chemistry changes all cause stress. These fish health resources are educational and are not a substitute for diagnosis or treatment by a qualified aquatic veterinarian.

Identify your fish

Knowing the correct species is essential before you stock a fish tank. If you are not sure what you have, the fish identification tool matches a clear photo against possible species. From there, open that species profile to research tank size, temperature, water parameters, diet, temperament and compatibility. Correct identification prevents serious mistakes, because visually similar species can reach very different adult sizes.

Fish care for beginners

New to keeping fish? Fish care for beginners comes down to a few essentials.

First, choose an aquarium large enough for the adult size and number of fish you plan to keep. Second, establish the nitrogen cycle before fully stocking it: beneficial bacteria convert toxic ammonia into nitrite and then nitrate, and in a cycled aquarium ammonia and nitrite should both read 0 ppm. Third, research every species before buying it, checking adult size, temperature range, pH, diet, temperament, minimum group size and compatibility. Finally, keep a consistent routine of feeding, observation, water testing, partial water changes and equipment maintenance. Those habits are the foundation of a stable, long-term fish tank.

Popular fish care guides

Detailed care information for the species people keep most:

• Betta fish care — tank size, temperature, feeding, filtration, behaviour, tank mates and common health concerns.
• Goldfish care — tank requirements, filtration, feeding, water quality, growth, and fancy versus single-tail varieties.
• Guppy care — tank setup, water parameters, diet, breeding, group management and suitable tank mates.
• Angelfish care — tank size, temperature, feeding, behaviour, growth and compatibility.
• Discus fish care — temperature, water quality, tank size, group size and feeding.
• Koi fish care — pond volume, filtration, feeding, oxygenation and long-term care.
