What types of fish require special care or specific water conditions?

Ah, the world of fishkeeping – a delightful hobby that allows us to bring a piece of the underwater realm into our homes. But as any seasoned aquarist will tell you, not all fish are created equal. Some finned friends require extra TLC and specific water conditions to thrive happily. So, if you’ve ever wondered, “What types of fish require special care or specific water conditions?” – wonder no more! In this captivating article, we’ll embark on a journey to explore these unique aquatic creatures and uncover the secrets to their well-being.

1. The Sensitive Souls: Discus Fish (Symphysodon spp.)

Meet the Discus fish, the royalty of the aquarium world, known for their striking colors and regal appearance. These beauties hail from the Amazon River Basin, where the water is soft, warm, and slightly acidic. To replicate their natural habitat, you’ll need to maintain water temperatures between 82-86°F (28-30°C) and keep the pH level around 6.0 to 7.0. Regular water changes are a must, as these sensitive souls are intolerant of poor water quality.

2. The Shy Perfectionists: Dwarf Puffers (Carinotetraodon travancoricus)

Don’t let their tiny size fool you – Dwarf Puffers have big personalities and even bigger demands. Originating from slow-moving waters in India, these little perfectionists need pristine water conditions to thrive. Keep the temperature between 74-82°F (23-28°C) and maintain a pH level of 7.0. These carnivorous fish love their protein-rich diet, so feed them a variety of meaty treats to keep their spirits high.

3. The Majestic Oddballs: Axolotls (Ambystoma mexicanum)

Axolotls are not your typical fish – they are actually amphibians known as Mexican Walking Fish. These fascinating creatures are neotenic, which means they remain aquatic even after reaching adulthood. While they don’t require specific water conditions like fish, they do have unique needs. Axolotls prefer cooler waters, ideally between 57-68°F (14-20°C), and they enjoy having hiding spots like plants and caves in their tank. Keep in mind that they’re sensitive to high levels of ammonia and nitrites, so a well-maintained aquarium is essential.

4. The Exotic Wonders: African Cichlids (Cichlidae family)

African Cichlids are a diverse group of fish that come in a stunning array of colors and patterns. Hailing from the lakes of Africa, these fish thrive in warm, alkaline waters. Maintaining a temperature of 75-85°F (24-29°C) and a pH level of 7.8 to 8.6 will keep them happy. However, African Cichlids can be territorial, so ensure you have ample hiding spots and space to prevent conflicts.

5. The Graceful Guardians: Seahorses (Hippocampus spp.)

Seahorses are a unique and mesmerizing addition to any aquarium, but they do require specialized care. These gentle creatures are poor swimmers and prefer calm waters with minimal currents. Keep the temperature stable between 72-74°F (22-23°C) and maintain a pH level of 8.1 to 8.4. Seahorses are notoriously slow eaters, so make sure their food is small enough for them to consume easily.


Q1: Can I keep Discus fish with other species in the same tank?

A1: While it’s possible, it can be challenging. Discus fish are generally peaceful but prefer to be kept in a species-only tank or with other non-aggressive fish that share similar water conditions.

Q2: How many times a day should I feed Dwarf Puffers?

A2: It’s best to feed Dwarf Puffers small portions multiple times a day, as they have high metabolisms and can become aggressive if they feel hungry.

Q3: Can I keep Axolotls with fish?

A3: Axolotls are generally not suitable tankmates for fish, as they may see them as food. It’s best to keep them in a species-only setup or with other non-aggressive aquatic animals.


As you venture deeper into the world of fishkeeping, you’ll discover a plethora of fish species, each with its unique set of care requirements. Understanding and meeting these specific needs will not only ensure the well-being of your aquatic companions but also reward you with a thriving and vibrant aquarium. So, whether you choose the sensitive Discus, the regal Seahorse, or any other fish with special care needs, let your passion for these remarkable creatures be your guide on this exciting aquatic journey. Happy fishkeeping!
