Heya, I've been thinking about stocking my tank with Pearls, but am not sure if I have the room. Apparently they do very well in harems of 2f 1m, but I've been told that would be overstocking by some and that it would be fine by others. What is the consensus here? Should I get a pair or a harem? Bonus points - what would be a good tankmate for this environment? Thank you!
