hey everyone. i have a question about my fahaka puffer. I just recently bought him at about 2 inches long from my local aquarium store. He adapted well to my tank and seems to be doing great. but anyways here is my question-- When will he be too big for my 10 gallon tank? i want to make sure he is comfortable where he is living. i arranged to sell him to a friend with a much larger tank when he is too big for mine. but i need to know how many inches is to big for a 10 gallon? also, in how long will that come around? thanks any help is appreciated. Oh, and whatever other info on fahaka puffers is awesome also.
