Congratulationsssss. Great looking Texas. You can do water changes, just do frequent small ones or dose with methylene blue to prevent any fungus forming on the eggs. Other than that Texas cichlids are pretty good parents. They'll take turns with the eggs, watch for them to fan the eggs. You could increase aeration in the tank.
Only thing to look out for is the female eating the eggs. She will pick off the bad eggs...just make sure she doesn't go crazy and eat them all. Keep us updated on the fry!
