I just got my first 'monster' fish tank today, I'll be setting up and cycling the tank this week. It's a 55g tank, I don't know the footprint. I'm looking to get a Gold Diamond Rhom at 3"-4" long. So, I'm wondering, will a diet of shrimp and beef heart be good for this guy, how slow will it actually grow, and will he be able to live any kind of algae eaters, like loaches, a smaller plecco, or smaller <1" gold algae eaters?
