I found i got a better survival rate leaving them with the parents, of course that depends on what else is in the tank, mine was dedicated to the b/nose.
Started out doing bi daily 10% water changes and had a 60% survival rate so changed to weekly water changes of 20% and ended up with close to 100% survival rate.
Found they were spawning every 3-4 weeks so it shouldn't be long and you will have plenty more fry.
Well done, cool fish i reckon : -)>
