My friend who thinks he knows about aquariums doesn’t

so my friend thinks that you cycle a fish tank in 1 hour and shouldn’t put food in and thinks my tank is over crowded (it isnt ) doesn’t know what a bactaria bloom is and provides no hiding spots its crazy and he thinks that gravel is bad for fish when he uses it for all his tanks and i showed him a pic and he just finds everything negative about it when he does it and he showed me his tank and its terrible… no hiding spots and the fish just stay at the top .. its so annoying
