Re: 88 degrees?? (none / 0) (#10)

There was research done on this subject in the eighties. Some of the breeders swore by 82 -84 degrees and others by 76 degrees, some even less at 74 degrees. The 'cold breeders' were convinced (for the sake of science) to up the temperature gradually in a couple of their tanks until it reached the higher degree, while the 'hot breeders' did vice versa. (Ceteris paribus, all other things equal) Each found that there were certain advantages to doing one or the other. One of the disadvantages, however, was the guppies in the hotter tanks had a shorter life span, as they matured and aged faster. (As a consequence of this you had smaller fish, as well.) Another interesting result was in the number of fry produced. The same fish produced more fry in the colder tanks but, had slightly longer gestation periods. Another disadvantage to this, and it wasn't mentioned, is that if you happen to need to raise the temperature due to an unplanned circumstance... you have much less playing room for temperature variance.
