If I am not mistaken the figure 8's are considered brackish, not sure about the red eyes. I know you can get red dragon puffers as fresh waters. http://www.thetropicaltank.co.uk/Fishindx/puf-irrub.htm here is a lil something on the redeye
Agreed. If you want freshwater puffer monsters, your choices are simple IMO... Fahaka or Mbu. And if you want a Mbu be prepared to get a monster tank that goes with the monster puffer.
Well Mbu and Fahaka are the monster freshwater puffers , but a good "mini" monster freshwater puffer is A.Modestus, or bronze puffer, they are great neon green and look like triggerfish, they also have the famous puffer attitude and teeth! I am keeping a 4.5 inch bronze in a 20 long. I hear that should keep him for life.
