I would caution you. I am a pretty experienced fish keeper and have had just about everything under the sun in my tank at one point or another, but a few months ago i purchased 12 Altums from a reputable supplier in Houston TX and only 2 survived. Everyone that I have talked to has a similar story to mine. They come in with damaged fins and get infections that are really difficult to clear up. I would definitely recommend that you purchase some TMP Sulfa from this website
http://nationalfishpharm.com/ and begin treatment as soon as you acclimate them. This is the only thing I found that clears up the baterial infections. Also turning your water temp down between 72 and 75 degrees will help more than anything. I know it sounds low, but the fish will be fine.....the bacteria will not be able to multiply at these temps. Good luck to you.
