Moriarty, you must excuse my ignorance. I was under the impression that guppies ate their young as a natural population control type thingy, not just if they were underfed. If you are seriously thinking of getting a hampster, be aware they have an average lifespan of just two years. (Not much of a return for the initial investment of the cage and other paraphernalia.) My kids had many hampsters during thier early years. The last one came to a very sad end....
It fell asleep at the wheel!
I believe people separate the sexes. Apparently its easy to sex guppies. To breed well you'll end up needing loads of tanks but you could just separate and stick to one sex, buying more when you're tank's getting empty. Never trust a pet shop to sex for you though. Most couldn't sex a shire horse.
We used to keep fish and Moriarty is right when he said to watch them is very relaxing.
We had neon tetras, absolutely wonderful bans of light shooting through the weed, and a black molly, angel fish,guppies,and a gorgeous siamese fighting fish,gourami and a massive sucking loach which clean the walls of the tank. With the right filters etc., they are easy to keep.
the only problem we had was when i bougt some weed/plants thingys it had snails on and did not see it..had ro rinse the gravel out in an old pair of tights in a bath full of hot water...and get new filters etc., never realised how quickly snails could reproduce either,..if I had the room in my living room I would probably get some again,
fish I mean not snails...
