Fish Fanatic
just wondered wether male guppies can be kept together and wether they would start eating my neons?? 

I would be more concerned with the neons attacking you guppies because guppies tend to be too peacful and even normaly peaceful fish have been know to tear up their tails and attack them. as for the guppies they should be fine as long as you have no females then they have no reason to fight over them
