What is a good legal freshwater predator for a 55gal? a fish that is kind of active. gets kind of big and is fun to watch while feeding!
A 55 gallon is only 13 inches wide. Mbu puffers (Tetraodon mbu) get over 2 feet long and fahaka puffers (Tetraodon lineatus) gets to 17 inches. Both are too large to be housed in a 55 for life.davo;666012; said:A puffer like a MBU or Fahaka. They are all the things you mentioned.
