IMHO buying something because the price was right could be a bad idea in the future. Make sure you know what your getting yourself into, buying an anemone for $20 is great but if it eats $40 fish not so good of a deal. That being said i have a condy and three small percs (all raised together and added to the tank at the same time) and they have no interest in my condy and he has no interest in them. Personally i would suggest if you cant monitor the tank closely i would not encourage them to host.
