Hi my name is Adam, I'm not a begginer at having fish i've had them since i was 5 and now i'm 13 years old! I saw these cute little fish called puffers in Petco, but i don't know if i should get 1 or 2 of them! Right now i don't have my tnak fully set up(29 gallon), and i'm also thinking of putting one of my special CT male bettas in the big tank also with my two beautiful HM females. Will this little aggresive fish kill my beautiful bettas in my tank or would they get along?
