What are L-number catfishes?
It is not so dreadfully long ago that lori?cariid catfishes were regarded as the poor relations of the aquarium hobby, and were maintained and tolerated in the community aquarium solely on account of their often bizarre appearance and their useful characteristics.
Many of the most popular tropical aquarium fish kept today are more brightly colored than their wild relatives. Modern techniques have allowed the development of varieties to be taken to new extremes, with the first genetically modified fish now available.
The popularity of fishkeeping
Although there is some archaeological evidence of fish-keeping dating back to Babylonian and Egyptian times, it is unclear when people started keeping fish for their aesthetic qualities, rather than as a source of food, but the activity certainly dates back well over a thousand years.
Micronutrients for aquarium plants
These nutrients are required only in extremely small quantities and are often described as "trace elements." They play important roles in the biochemical processes that sustain life and are vital for good plant health.
