Everything You Need to Know About Nerite Snails

You’ve spent hours assembling and decorating your freshwater aquarium – you’ve even gone through the length process of cycling the tank and slowly adding fish. Your tank is beautiful and thriving, but it may not stay that way for long unless you keep up with routine tank maintenance.

As an aquarium hobbyist, maintenance is absolutely essential for the wellbeing of your tank and your tank inhabitants, but you don’t have to do all the maintenance yourself.

Aquarium Hobbyists Help Save 30 Species from Extinction
The pet trade gets a bad rap for exploiting wild animals but sometimes the opposite is true. Aquarium hobbyists have played a role in preserving 30 species that have since gone extinct in the wild.

There’s a great deal of controversy surrounding exotic pets like sugar gliders, slow loris, and big cats. Animal rights supporters claim that wild animals belong in the wild and keeping them as pets is cruel. There is a difference, however, in keeping a wild animal as a pet and protecting endangered species by breeding them in captivity. Conservation breeding programs have saved a number of endangered species from extinction including the Arabian oryx, Przewalski’s horse, and the California condor.

While the practice of keeping wild animals as pets is often more harmful than helpful, it isn’t always the case within the aquarium industry. In fact, the aquarium hobby has helped bring 30 species of wild fish back from the brink of extinction.

Is the Aquarium Hobby Helpful or Hurtful?

The truth is there isn’t a simple yes or no answer to this question. When it comes to the preservation of natural populations, there are certainly instances in which the pet trade has been part of the problem.

For example, when the movie Finding Nemo was released in 2003, it led to a sudden spike in the popularity of clownfish. Increased demand for clownfish in the pet trade led to an increase in wild capture, causing clownfish to all but vanish from many areas. Some areas still use cyanide to capture fish for the aquarium trade as well which can be damaging to coral reefs.



Another problem with the aquarium trade is its contribution to...
