I used to keep them and they even breeded in my tank. But back then, I added salt everytime I change the water. But you can't add salt to a planted tank. Another thing is they are meat eaters. So you have to add live food for them and this may pose potential nitrate problems to your planted tank. Another consideration, they will "ambush" shrimps from behind and "kaput" them.
But the good news is they can be kept with tetras BUT they are slow eaters compared to tetras. So may be quite hard to ensure they have their share of food. Lastly, they are territorial against their own kind but that should not pose a problem if your tank has "crevices" and space for them to own!
Hope it helps!
Cheers!
