I have a single Male Veiltail Betta in a five gallon tank. For decor, I have a small ship, two plastic plants (which are harmless), and a small blowfish (decor type). I also have a Whisper filter. I want to know if it is safe to add One Cory Catfish and Two Cherry Barbs. I also want to know what types of foods to get for the Cherry Barb and Cory Catfish (food I can buy from Petsmart or Walmart). Thanks.
Update:I thought it over and instead I am adding Two Cory Catfish and forgetting the Cherry Barbs. Can you please tell me if this is okay instead. Also, please tell me what type of food to get from Petsmart or Walmart for the Cory Catfish.
