Hi everyone I am going to be making the switch from freshwater to saltwater in little bit. I plan on setting up the Red Sea Max 250. My daughter is obsessed with puffer fish, loves them, which is part of the reason for the switch. I assume that a dogface or a porcupine will be too big to the 65 gallon tank, what I'm wondering is if anyone can give any recommendations for a dwarf or smaller puffer that would work in the tank, or let me know if I'm wrong and that one of the other two would thrive in this size? Thank you and look forward to everyone's opinion.
