I have 3 in tank. Have had for almost 2 years now. I think if shipped well (you cannot control this), acclimated well, and put into a VERY heavily planted tank witjout anything to harass them they would do just fine.
PS--I have 3 zebras, 4 regular, and a red-eye in my tank with 3 very large angels and have never had a problem. I even have about 20 cardinals in the tank too.
