So, after much research and consideration, I have decided that this is a problem that I am not able to figure out myself and I would really appreciate some advise from some more experienced fish keepers!!
I have a give gallon tank with three guppies in it (one male two female). They are pretty stock standard guppies, not fancy ones (as far as I know?), they don't have fancy tails, just short rounded off ones.
I wanted to add something else to the tank and eventually decided I would try a betta fish, put a male one in there hoping he would have a good temperament. They were all great for the first several days until he got comfortable and took a chomp out of the male guppies tail! So I have moved him out. (Found out later a five gallon is too small for a betta and other fish anyway - so theres another lesson I've learned).
Anyway my question is, am I able to put anything else in with my three guppies other than a couple more guppies? Everything I have researched is either too big a fish at full size, or is a schooling fish and requires at least six which I don't think I can fit in there. =( I was looking at tetras, neon tetras, white clouds, and some other options but none seem to be quite right. =S
