Well now that I have my filter starting to cycle I was thinking about what fish I will want to get for my tank. First things first... The Tank: 55 gal. 48"L x 15"W x 18"H Rena XP3 Filter Sand bottom The Fish: 2 Blood Red Parrots 5 Ghost Catfish 4 Flame Dwarf Gourami 5 Scissortail Rosabora 4 Opaline Gourami Using the AqAdvisor the only warning that it came up with that the BR Parrot would be too agressive for the Glass Catfish and the Dwarf Gourami. The second thing that made me a bit curious was that it said that I would be needing to change 1/2 of the water out each week. So anyway I want to stop by and see what everyone thought.
