THE SHOCKING TRUTH ABOUT ELECTRIC FISH

 ELECTRIC FISH

For aquarists looking for an unusual pet, few creatures are as fascinating as electric fish. But can you safely keep them in a home aquarium? A classic reader question delves into the realities of owning these living power generators.

A Reader's Question on Electric Fish: "I would like some information on the Electric Catfish. Can you give some idea of other kinds of fish that discharge an electric current? Would it be wise then, to keep them in an aquarium with other fishes?"

The Powerhouses: Electric Catfish and Electric Eel

1. The African Electric Catfish (Malapterurus Electricus): This species "grows to about two feet in length and lives exclusively on small, live fishes." Its powerful electrical system is a key feature: "Its electric organs... serve as an attack/defense system... and the creature can discharge between 100 and 300 volts, depending on its size."

2. The Electric Eel (Electrophorus Electricus): Even more powerful, the Electric Eel's shock is legendary. "The main electric organ is capable of discharging 600 volts, and while humans are rarely killed by the shock, it can be fatal to animals as large as horses."

Can You Keep Electric Fish in a Home Aquarium?
This is the critical question for aquarists. The answer involves understanding their nature and needs.

- Young Electric Catfish: Young specimens are quite peaceful with similarly sized aquarium fish.

- Adult Realities: A major warning follows: "Due to the adult feeding habit... few aquarists are equipped to keep this fish when large." Their predatory nature and significant electrical discharge make them unsuitable for a community tank. This is why "they are commonly found in public aquariums abroad," like the London Zoo, which has special equipment to detect their discharges.

> "These are not sufficiently powerful to generate noticeable shock, but are used by the fish to orient in murky waters."
These fish use a weak electrical field for navigation and communication, posing no threat to tank mates or their owners.

While the idea of an electric fish is thrilling, they are not typical pets for a home aquarium. The powerful species, like the Electric Catfish and Eel, require specialized, large-scale setups and are best left to public aquariums. However, milder species like the Elephant Nose can be a fascinating and safe addition for experienced aquarists. 
Note: Always research thoroughly before introducing any unique species to your tank.

IMPORTANCE OF NATURAL PLANTS I

                    WHY USE NATURAL PLANTS?       The use of live underwater plants in home aquariums has been fully explained and documented in many advanced countries of the world where the hobby "tropical fish keeping" holds a second place.          Majority of aquarium keepers in the country are fond of using plastic plants rather than real live aquatic plants. This could probably be the major reason for the unending fish deaths, cloudy water and the production of fetid odor from the aquarium water. In an effort to solve these problems I shall endeavour to put before the country's aquarists the true value of natural plants in the aquarium.          One of the most important functions of plants lies in the release of fresh 100% pure oxygen into the tank as a by-product of photosynthesis.           This aids fish-breathing and as a result the a...
