You should have wigglers in a couple of days, the parents might hide them from you. 5 days or so after they are wigglers they will be free swimming. They'll eat their yoke sac until they can swim. I've never breed texas before but I imagine they are great parents like similar cichlids. I'd leave them with the parents as long as possible which could be months if you are getting the other fish out of the tank. The fry will eat what comes out of the parents gills to suppliment what ever you give them. Unless I'm specifically breeding a fish I don't feed the fry, I let the parents do it. I also don'ts clean the glass on their tank as the fry will eat the algea and infosura (sp) growing on it. My fry tanks look dirty but have really clean water. I also put a small sponge on the filter to keep them from getting sucked up. There's a 100 ways to raise fry, you'll figure out what works best for you.
If this is their first time they may eat the eggs or wigglers, but they'll spawn again.
