i have had a Jewel 180 tank since Sept 2006,it has various fish,white
cloud minnows,serpae tetra's,rams etc...,i had 4 angel fish when i
started the tank but 1 died leaving me with 3,2 seem to be together all
the time and the other 1 just keeps to itself usually,would it help if
i bought a similar sized angel fish to keep the other 1 company or
would the others attack it being a new arrival to the tank??
