Best Temp for Tumbling Eggs?

Best Temp for Tumbling Eggs?
I am currently tumbling Frontosa Mpimbwe eggs from wild caughts. The adults are in a tank at 77F.
My tumbler is in a 10 gallon tank also at 77 degrees.
They are developing fine but I had heard that with a slightly higher temperature, fry develop faster with African cichlids. Is there any truth to this? How much higher would one go and is it worth the risk?
135 Gallon: Frontosa 5 Wild Caught Mpimbwe
90 Gallon: Cyrtocara moorii, Labidochromis caeruleus
90 Gallon: Cyprichromis Mamalesa, Enantiopus Kilesa
10 & 20 Gallon: Fry Tanks
Fish tanks - betcha can't have just one!

As a general rule, fish, plants, bacteria, and yeast all tend to develop more quickly at higher temperatures within their tolerance limits. A shorter life span and a smaller maximum size are also the general rule with elevated temperatures. You are already near the high end of the temperature tolerance for Tropheus. The higher the temperature, the less oxygen can be absorbed into the water, so that's another reason to stay where you are or even back off to about 75.

Tropheus eggs are already a little delicate for tumbling. A tumbler that keeps the eggs moving in suspension without bumping against any part of the tumbler is worth the higher price.
