Ive got a ten gallon that is overun by guppy babes, I planned on bringing them to the pet store to rid myself of them-they are all that are in this tank for fish. Problem is that they just reproduced before the original babes are of a size to bring to the pet store. So now I am inunated with guppy babes. I have in a 55 gallon, 2 BR's, one is adult size, the other is about half dollar size. How stressful would it be to put one in the 10 gallon to take care of the guppies? And which one should I use, the small one or adult size BR? Thank you.
