I am getting a 150 gallon from a friend and he has: 1 Florida long nose gar 12", 4 Dinosaur bichir around 5", 2 Raphael catfish 3", 1 African brown knife fish 6", 3 Blue gills 5" -8", 1 Peacock Eel 6", 1 Plecostomas 10", 1 Pangasius Catfish 4", 1 African Featherfin Catfish 7", and 1 Red Oscar 10". I was hoping to get some more information on this selection on fish. I have been unable to find much on some of them. for example over all size they will reach, if they are a good mix. I understand I will have to get a bigger tank asap for the hole tank to stay together.
