If you saw pictures of Byrons tanks you would know they are far from 'hum drum' or 'plain jane' they are some of the most successful and beautiful tanks on this forum.
Your fish could easily be considered plain jane... in all honesty you can walk into any shop and find Angels, Oscars, Red Tail Sharks and chuck them in any size tank and a certain percent of the time it will be fine to the average, low skilled owner. The thing is with this sort of approach is that you will run into problems every couple of months, might not always be something major but there will be something that will affect your fishes quality of life. If you try and keep fish that are realistically beyond your means just accept it and find an alternative, why try and keep 4 Red Tailed Sharks together when there are so many interesting Loach species that look very similar and will actually thrive in a group.
The thing with people truely dedicated to moving this hobby forward like Byron is that you can choose to listen to them or not, but I know from experience that when you choose not to they wil be proved right eventually. And its upto you to understand the advice you are given and then work in those parameters to make the most successful enjoyable tank you can. Like I say, 4 Red Tailed Sharks in a small percentage of tanks will work fine but you can get these anywhere, you could have chosen to research what you wanted and tried to source and keep a group of Yasuhikotakia loaches together and achieve a very similar look and level of activity, but be more sure that those fish will live out their lifespan in a healthy way from the moment you put them in the tank.
Choosing to not research, respect or act responsibly to your fish is no excuse for trying to create an 'exciting tank'. There are always alternatives to achieve what you want to achieve in your tank if you spend the time educating yourself how to do it.
