(guppy+fancy guppy+2 endler's guppy)+5G=??
 

Is it ok to put a regular guppy, a fancy guppy, and 2 endler's gupperys in a 5g tank (sand substrate w/ MTS, and maybe ramshorn)? I want to put guppies in my empty tank, and I want some variety.

Thanks!:-D

No ,fish will crossbreed and produce possibly too many babies for 5 gallon tank.

I want all males.

Tank too small ,males will fight ,rip fins of other males.

How about 3 male guppys/fancy guppies?

You could try ,but I would be negiligent by not mentioning that males of nearly all livebearer's will in the absence of females,nip at each other.The larger the tank ,the easier for the fishes to avoid each other.
I would see that the tank had plenty of floating plants for fishes to escape/hide if needed.

I'll just do 2 guppies. I'll give them places to hide if need be. Thanks!

I have a couple male guppies in a 5 gal tank and they never nip each other :P

anybody know if two black skirt tetras will fit in a 5g?

No, they certainly won't. They are a shoaling species, which means (usually, and in this case) that they need at least 6 of their own kind. Black Skirts reach 2 1/2", being among the larger tetra, so a 20 gallon tank would be minimum.

btw, this is a really old thread for anyone wondering why I am asking about guppies LOL.
