Help fast! I just bought 10 guppies (5 male 5 female) from the LFS. I set up a new aquarium (1.17 gal) and supplied it with a submergable filter, and a large plant to provide cover for the babies. I have thus far lost 6 of my adult fish, yet there are babies in my small tank. I intended on using this tank to breed Guppies for my oscars. The water I am using in my new tank has allready been cylcled as it is from my established 33 gal tank. What do I do to stop the death in my small tank. The water isn't heated as the LFS told me you don't need a heater for guppies. Theire is a plentiful supply of oxygen, what do i do?!?!?!?!?!??!
