delayed

I don't know if this is the exact, correct term but its a spawning process I've recently been able to witness with my 90g New World tank. I've had many typical maternal mouthbrooding African cichlids, but this is my first experience with delayed mouthbrooders. This is actually the second spawn...

We look to be having an out reak of ich, the infected fish is anew one.. But we quarantined for a month and nothing appeared a miss. Anything else we should be looking for or concerned about?
