Hatchets OK in a trio?

[AsahiToro]

I understand these guys like to be in groups. I want to hang some java moss or some other surface type plant(suggestions?) over my spraybar so that it trickles across a portion of the top of the tank. Would a few marbled hatchets look good in there or do I need a bigger group for them to be happy? I'm trying not to overstock while still having a little diversity. Thanks for any input,

Scott

3 would be OK, as a minimum. I had 3 in a 10 gallon tank a while back and they did pretty well (until they jumped out of the tank!). Just don't keep the tank lid open for too long as they are excellent jumpers!
