local temperate species surving in heated tanks

[o.c.d.]

So let me see if I have this correct a Figure 8 or greenspot puffer can adapt to a salt water environment. But FW puffers CAN NOT BE DONE! Is a greenspot or a figure 8 a puffer? If they are a puffer than Cannot be done is a contradiction and my generalization of all puffers should be corrected. I really didn't mean all puffers I meant the one the LFS employee showed me and said " these little guys can be converted to SW"... Thank you for showing me the way midgetwaiter
