I just wanted to let everyone know my puffer is alive and doing very well now. Purchased him 4 months ago and had him in 5 1/2 gallon tank with aquarium salt(If any of you puffer fanatics remember the troubles I had). With some time I slowy acclimated him to the proper level of instant ocean and moved him into a 10 gallon tank for now. He is in great shape (about inch and half long) and has an excellent personality, and loves eating frozen shrimp. I just wanted to let everyone know, since many people told me he would die...hes been a strong little guy. I have plans of moving him into bigger tank come christmas, what size do you puffer experts reccomend?
