Is three a crowd?

[jwill275]

I was able to pickk up two mature Perculas for my 125 DT. I originally had two but one committed carpet suicide about 6 months ago. The single fish is doing well. Should I be concerned with having three, the two I picked up seem to be a pair. Should I look for another similar (slightly smaller or larger) for my original fish or will the three live in harmony. It's only been a day but I see no sign of agression, in fact the single fish appears to be very happy to have the company.

There always exceptions, but IMO/E, it is best to stick with one pair per tank. This might work in the short term, but once the pair starts to spawn, they won't take too kindly to the 3rd wheel.
