the male guppies will declare war on each other and chase each other around to the ends of the tank... lol....

And if u want to stop that, you need to introduce a few females... well more females then males... and then the guppies will breed like rabbits and crush your bioload in less then 4 months.

hmm, I've heard keeping all males guppies was fine :/

yeah so did i, until u goggle kissing male guppies and read how many people see that happening.

at first you think its playing, until you see some of your males with tails ripped :\

The kissing is a declaration of WAR... and no im not kidding.. :\

make sure the pleco isnt a common pleco and its a bristle nose pleco.

theres a hugh difference..

the first one can get well over 2 feet... its typically that big fish which u see in youtube thats almost half the length of the tank.

The second one has a growth cap of 6 inches i think.

meh.... but pleco's in general produce enough waste to rival a goldfish.
