+ a pleco,brown hoplo,and an iridescent shark(yes i know they get like 5 feet long but mine only gows an inch every 6 months and is 6 inches long

Overstocked. I was going to say perfect (though could have had more tetras) until I saw that you added stuff in the description. Each one of those in the description can get pretty huge. The side of food fish. I hope you realise that. You can probably get away with one, maybe two but 3 is just pushing it, especially since no.3 is a shark. I hope you have a place planned for it as it gets bigger.
