Ok. I know that I was told that my tank is "full" but I had to make this adoption. A guy came into my LFS when I was there getting dog and cat food (I figured that it couldnt hurt to take a look at the fish ) He was moving and couldnt keep his 3 Firefish. They are pretty small. My LFS couldnt take them cause they just got a fish load today and there wasnt room and John (the owner) wouldnt allow it cause they had some of there own already. I looked at the fish and they seemed pretty healty so I took them (I also had one of the guys that works there look at them; he is a marine biologist so I trust him). Should I really not add them or are they going to be fine?? I really like them so I would like to keep them. What do you think??? Tank inhabitants are in sig.
