Yeah I hear ya Pat, the 65 is a 24inch tank I believe but it would be crammed either way which is why I'm probably going to just stay with the discus for now. I enjoy them so no real reason to get rid of them but I do want to eventually try altums. Thats one of the things dale mentioned was about the angels gorging themselves on anything possible vs. discus eating gradually... Well except mine who fight over the food lol lol. I will just keep these guys and slowly trade out the heckels for reds come the new season and once I'm in my own home and what not and can fit a 220 or so I will get altums, I just wanted more of a challenge because I love doing what people say is so hard lol.
