The puffer and axo may become aro snacks

puffer needs to be brackish or full salt later down the line.
axolotl is cold water and can not be housed with any fish
what so ever. it will die from stress from having it's frills
constantly picked on or if the fish is small enough it will
eat the fish. axolotls should only be housed with other
axolotls in similar size range.
