So this is the story. I have a 20 gal, now only home to two female guppies after they attacked and killed both the male and my hope for babies and it also is home to my Peppy, a peppered cory. I have set up a 30 gal (after which the females killed the male guppy, great encouragement huh?) and I have already ordered blue delta guppies and nice yellow guppies, I am gonna have a few ramshorn snails and trumpet snails in it and also some cherry shrimp. I was thinking of some tank mates and I came across bristlenose plecos but I cant find that much info..Would they be peaceful along with the guppies and cherry shrimp in the 30gal? and any suggestions for other tankmates that are peaceful fish? also any ideas on what to do with the two female guppies in the 20gal is appreciated..
