Ammonia is deadly. Nitrites are Deadly. But Nitrate is safe right, no afraid not, but what can you do? 

Which is the most important, quick results or fish welfare. 

With Florida looking to introduce white lists I have a ramble on about what this could mean, and what this means for our hobby. 

A gill-bearing aquatic animal right? Not really there's a load of fish that don't obey the rules. 

In 1976 the Royal Aquarium opened, the fact they didn't have any fish seems to be the least of their issues, dead whales, serial killers, and so much more. 

What is a fish? An aquatic animal with gills, but what if they decide to climb out of water, which species do this, and why?

Sorry I dove into the science, and I may have gone too far, but there's a fair bit here that you need to know about your tank, and what's going on. 

Some fish live in the extremes, so why can't modern day fish start the adaptation to living in warmer waters that dry up seasonally. 

We tend to rant about how bad genetic modification is, and these fish are illegal in many countries, but are they the worst thing in the hobby?

You bring a new fish home, is it safe and healthy to go into your tank? How do you prevent an expensive mistake?
