7.4 pH is fine, red head geos are pretty adaptable to pH in my experience, high 7s or 8 doesn't bother them. 76 F is a couple of degrees on the low side imo, their native habitat is warmer according to the literature I've seen on them, I kept mine 78-80.
10 gal tank should be a very short term setup, they need a larger tank. For one thing, they're active fish and need space. For another, it won't take long for them to grow enough to be cramped. Red head geos don't do well with stress or low oxygen, odds for both are increased in an overly small tank.
Feeding-- The objective is not to get their bellies to bulge, if they do you're overfeeding, an even worse idea in a tank's that's too small. It won't make them grow faster, just makes for inefficient digestion and more waste-- aquaculture science studies have demonstrated this many times. Body shape should be a guide to how much to feed. Bellies too rounded = feeding to much. Concave bellies and you can feed a little more. Depending on species, flat to only slightly rounded bellies is about right. This is true of most fish and includes red head geos.
They will be happier with some sand to sift, it's closer to their natural behavior. All my tanks are sand. If you do it right, don't overstock, don't overfeed, sand isn't hard to keep clean ime.
I kept and bred these guys for a number of years, these are just some basics if you want them to do well.
