http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=spiny-box-puffer-question#1 i just got a 6 inch puffer fish and put him in my 30 gallon tank. he seems a bit anxious, and has been swimming quickly back and forth all day. is it just because hes not used to the tank and i should give him time to adapt, or is the tank too small for him to live comfortably? any feedback helps thanks kdg123 2010-11-07 http://forum.aqua-fish.net/?topic=spiny-box-puffer-question#2 Is there plenty of rockwork in the tank that he can use for cover, this often settles fish quicker. The tank will need upgrading as the Puffer grows mickey 2010-12-03
