As some of you know i am in the process on getting a 300Gal tank which my current fish will be going in see sig' for my fish , but i would also like to add a couple more fish in there when i have the tank all setup and i have been looking at a website that i can get RTC's off along with Silver Arowana's - But do you all think i could get one of each and keep them both in the for life ? Also are there both fast growers ? As when i/ or if i get them both they will only be about 3 - 4inch in lenght .
