Thank you all for your advise. From the looks of it, I haven't lost a single fry yet (unless Daddy Max consumed a few, which is more likely the case) and they are happily free swimming being all kinds of cute. I did a rough count and there seems to be about 150+.
I have another question. To keep the bottom of the tank cleaner, would it be wise to add a bottom feeder? I have two mystery snails, some cory cats and a couple plecos. Would any of these be a suitable tank cleaners or would it be best to just stick to siphon cleaning only?
I'm sure this has been answered many times over but I didn't stumble on any forum topic.
