I was wondering i have 2 domino damsels in my tank,have had it running for about 2 months,are they any fish i could put in their with them,because i know they are aggressive little boogers. I dont have any coral,going to make it a fish only tank for now,until i get the money later for the light. I was thinking about maybe purchasing a golden head sleepy goby,i think they are awesome little fish,would it be ok to put one of those in their with the damsels. If any one knows i would really appreciate it. thanks
