New to discus

I received 40 discus fry from a friend, they are 5 weeks old and in a ten gallon bare grow out. Running a heater and sponge filter, 84 degrees (same parameters they were born in and parents kept in.) I have lost a few fry over the past 2 weeks but nothing I would consider concerning.
They will be getting moved into a 30 gallon tank in a couple more weeks. Eating baby brine shrimp 3 times a day.
Any advice on things I should be doing in regards to my over all success. I will upload pictures later, stuck at work currently.
