Hi Joe, cute little buggers. Not sure if you need to hear this from me but since you have not had discus this small I will offer these suggestions. Careful not to overfeed and watch for ammonia since you just upped the bio-load in the tank. I am pretty sure others will suggest larger water changes but guessing you are following the suggestions from your breeder. Best of luck with these little ones and look forward to seeing them grow.
Pat
