I would agree except that far too many people equate spending lots of money with being an expert. Have little patience with noobs and people who aren't experts making well intentioned mistakes and also make little effort to accommodate the person and their individual situation. "As it is"? Oh really? So this much vaunted technical background you claim is where exactly? I've had many (too many) long decades in this hobby and I fail to see technical expertise in telling some new person what they can't do and then leaving it at that. Bullshit! The Smug and Shrug? Most of these 'technical background' folks usually have a canister filter and a CO2 emitter and think that is the ultimate in knowing how to care for fish. Why did they bother chirping in at all if they weren't going to use this alleged technical expertise (what the hell does that mean anyway? Most experts in here do weekly and often twice weekly water changes and some do daily water changes and if that is being an expert then ... ! I've seen a rare few experts in this subreddit but most have the personal dignity and self assurance (they don't need to prove they know more than does some noob) not to discourage someone new to the hobby. Moreover they constantly tell people to take fish back to the LFS. The reality is that most if not all LFS will simply dump the returnees into a feeder tank or just dispose of them rather than risk introducing a disease to the store's tanks. These folks... these experts like to pretend that that doesn't happen so they deign to offer this as advice. They are full of it. Technical backgrounds? Only according to them anyway. A biologist has a technical background ... a closed water systems hydro-engineer has technical background... reading lots of websites and then repeating back whatever they say without the personal experience to know whether what is said is true or not and having a few tanks does NOT qualify as a technical background. People like to show off (a version of passive aggression) where they'll announce that they have a $1,000 set up as their qualifications to answer a question by a noob who just bought a 10 gal tank. It's not being rude...it is being... absurd and all too obviously they have something to prove or think that their having spent that much money makes them special. Maybe they just want someone to care that they've spent all that money and will pout if no one tells them how impressive they are. Just reading their answers shows you that they don't really know all that much at all btw. If someone doesn't want to help with someone elses's tank problems ... then WHY did they stop to post a negative comment? To feel important and nothing more? Why respond to a request for help and then not help and in fact discourage? This person saved four fish from certain death and I happened to respect that and their intentions. But technically...what do I know?
