Thanks for your encouragement guys! Before I read these latest responses I decided to put the Leps back in the breeder with the Cone. So we are all on the same track.

I've moved the fry to a smaller tank but I think that project is a failure. They are just past 5 weeks and still .5" fish!

I will be doing something different this time. I will be keeping the parents in with the fry at least 5 to 6 weeks. I have seen hobbyist here do it - so I will give it a try as well. Perhaps that period between 8am and 5pm will be all the difference with the parents in the tank to feed off of.
