Yea, I just purchased some eggs online and going to give it a shot. Noticed the make with what looked like a huge mouth full the other day. After watching him for a bit I noticed small little pebbles in his mouth.
If you can get a breeding net and just scoop him in it without changing tanks you’ll definitely have a good survival rate. Try doing this around day 20 because he’ll be letting them go as they hatch
It’s up to you, either will have escape routes for bbs as long as the fish can’t get threw. You can always setup a little 5/10 g tank for grow out and not have to worry about food getting away
