i currently have a 90g(but will be upgrading to 125/180 come tax returns!) with a 17" aro,12" ck, 10" gibby pleco, and a blood parrot and am thinking bout getting a catfish but i dont know what will mesh with what i have already. in 2to3 years i will be upgrading to atleast a 300g, more if needed or an indoor pond. i must upgrade my tanks in steps due to money- but rest assured i will not skimp on my plans! i was thinking a lima shovelnose, i hear they dont get to big to eat my fish or a rtc but they get huge right? how is a rtc's attitude and how big do they get in an aquarium, ive seen huge ones come out of rivers but never over 2.5' in an aquarium personally.any other suggestions,info,and pix would be appreciated.
