this question gets asked a lot but, what are some preditory of aggresive fish that can live life in a 4'x18"x2' 90 gallon tank. i want something thin and long. almost garlike in apearence maybe? thanks for your help.
Great list, the spotted pike characins are as garlike as you can get and a group of 3-5 would do nicely in a 90 with maybe 3 redhooks and a catfish or two. this pic is by OTT
