Have a look at Nobody of the goats comment for starters
"So because it is unnatural for fish to be housed in tanks, that makes it fine to add them to a tank where the filter has no bacteria colonies to deal with the extremely toxic waste that fish naturally produce, rather than responsibly preparing the tank and filter by "fishless cycling" in advance of the first fish additions?"
This suggests that im an irresponsible individual who has no concern for my fishs' welfare
"Following on from this, the next thing you will come out with is that you use tap water in your tank without dechlorinating it first, exposing your fish to toxic chlorine (burning their gills away)... A bit like me dumping you on Venus without breathing apparatus and watching you suffocate due to sulphuric acid levels in the atmosphere"
This suggests that not only have i no clue of what im doing, but its ok to mock my intelligence, and that ive gone into a pet store, asked for a tank, chucked some water and fish in it and hoped for the best.
So these types of think they no it all individuals are out there, pointing the finger.
