We are trying to help you here. We are telling you to get smaller fish for good reason, big fish tend to stress out and die in tanks too small for them. No matter how much love and attention and planning you put into getting a fish, if the tank is too small that fish is going to be unhappy and stressed with 99% of the time will lead to its death. There currently is a guy on here who has a puffer and foxface in a 55, and they both have ich, and im pretty sure he lost both of them. Fish can normally fight off the ich on their own, you usually only see symptoms when they are stressed.
We are only trying to save you from that.
And many many people post on here that they are going to give them away or upgrade their tanks when they get bigger, and we look at that statement with some skepticism because they hardly ever do. Or they do it too late, like the foxface and puffer dude, he has plans to upgrade his tank - in a month, but his fish are too large now and are suffering.
Also im very confused by what you mean you want experience with different fish as a way of working towards a goal?
We dont mean to insult you or make you mad, you came to use for advice and we gave it to you. We gave you some great suggestions, you told us what you were thinking and we told you that probably wouldnt work. And dont feel bad about the video, lots of people get that or the "tang police" (you should search it on this forum, its very common and pretty funny) because lots of people have the exact same idea as you did and we just let them know it isnt a great one.
We will help you set up a great FOWLER tank, go check out those lionfish, that would make a really cool species tank, or those anglers!
