Fish For A 5gal

[MHunt]

guppies are much too active for a 5 gallon

And too big in the long term. And males only in a tank that size (cause you really don't want them breeding in there!) would end up fighting.

As stated above guppies are too active for a 5gal. Sorry And i really think the beauty of guppies is at its fullest when in a larger group. So a bigger tank is really a must.
