WHY DID MY FISH DIE? SOLVING THE MOST COMMON BEGINNER AQUARIUM PROBLEM

LETTER TO AQUARIST

Welcome to our "Ask the Aquarist" column, where we tackle your toughest fishkeeping questions! Today, we're addressing a heartbreaking but incredibly common problem from a fellow hobbyist: "Why do my new fish keep dying within a few months?"

 Mrs. Chyoma Onyenakazi from Owerri, Imo State, is a classic case that many beginners face. She wrote to enquire why her fishes did not stay up to six months in her aquarium before they died. She wondered whether the fish died because she fed them with cornflakes or because she didn't change the water for about seven weeks. She also wanted to know how to detect that the fishes are sick and the type of treatment to be employed. Let's dive into the real culprit and its solution.

Dear Mrs. Chyoma

The Real Reason Your New Fish Are Dying

While feeding fish cornflakes is not recommended (they need specific nutrients), the primary cause of fish death in new tanks is rarely a single feeding mistake. The true enemy is invisible: a build-up of toxic waste.

In a closed aquarium ecosystem, three things produce waste:

1. Fish waste (urine and faeces).

2. Decaying, uneaten food.

3. Decaying plant matter.

Infrequent water changes (like waiting seven weeks) allow these toxins to accumulate to lethal levels.

How to Detect a Problem Before It's Too Late

A "sick" tank often shows signs before fish start dying. Watch for these red flags:

* Fish Gasping at the Surface: This is a major sign of oxygen deprivation, often caused by nitrite poisoning.

* Lethargic Behavior: Fish sitting at the bottom, not swimming, or lacking interest in food.

* Cloudy or Murky Water: Often a sign of a bacterial bloom, which can coincide with an ammonia spike.

* Clamped Fins: Fins held close to the body instead of being fanned out.

The Natural Solution: Preventing the Problem

The best way to manage waste is to recreate a natural ecosystem in your tank. This is where the advice about "real-life underwater aquariums" and plants comes in.

A planted aquarium isn't just for looks; it's a functional filtration system:

* Live Plants act as a natural filter, absorbing nitrates (a less harmful byproduct) as fertilizer to grow.

* They compete with algae for nutrients, leading to a cleaner tank.

* They oxygenate the water for your fish.

* They provide hiding spots, reducing stress for your fish.

A well-planted, balanced tank is easier to maintain and creates a stable, healthy environment where fish can thrive and even breed.
