The Puffer Forum

My Little GSP has decided he prefers to be a loner..any others I put in there, sadly expire soon after... He is territorial-even in the big tank... he likes when I come visit his tank! Turns from black to white in seconds! Lately, he has been turning a golden color, as oposed to his beautiful neon green... is this a problem with his health or his environment?

A lot of puffers prefer to be alone.

Can't really say how his water quality is or isn't unless you provide us with results. We need ammonia, Nitrite, Nitrate, and salinity.
