see, i've kept discus before, *if u look at the link in my sig* and i've kept 2 ..it was a disaster, the one that is more shy, kept on bein picked on..until he died.... my other one however is fine.I got rid of him because i had 100 gupies waiting to get in my 55G and i want my gupies to be able to breed and i dont have to scoop them up and stuff. How peaceful are the cardinals? people say the rasboras were peaceful..well..they arnt, the nip each other..and the weakest one dies...then the next weakest..i'm down to 1 now and he is fine on his own..so obviously it's the other rasboras that kept on pickin on him. are cardinals the same?
EDIT: i've kept the discus before..and the one left on his own was healthy and thriving, they are not only not hard to keep but easy, a good filter is what you need, i'm not talkin about the wild ones though. Once they get used to your water, they arnt that hard to keep at all. Btw i can get them for $20CDN ea, got yellow ones..blue one red ones...
I might just get a blue one or just a red one, i'm glad to hear that they wont conflict with the cories, not even a lil bit, the cories are the main specimens in the tank..usually it's the discus, but i'm a cory keeper. I also hope the cardinals wont nip my cories.... If even one person has any experience with nipping cardinals, please post, i mean they are in the same family as pirahanas
