ok, i have 1 pregnant female guppy in a u.s. 2 gal tank i had a male which died before i got his treatment. i have had the female for about 2 weeks she is healthy as an ox i change about 25% of her water every 2 days all the equiptment i have is an air tube to oxidize the water and water conditioner. i am turning her tank into a fry tank and moving her into a 10 gal which i will set up with other fish i want to get more guppies and what would be some aquatic animals i could put in that are cheap and not fish?
