Also. I just found your channel I noticed you haven't made a video in awhile. Do you have a FB page so I can gain knowledge from someone like you with a lot of fish keeping experience??
Just apiece of electrical wire about a foot long or so, put through holes at the open end of the bottle to make a hanger. Then a J-hook screwed into a shelf that's overhead. I hope that helps.
Interesting! Possibly. Or at least very close. I don't have too much in this one. I'd love to see the hatchery you bought on Ali Express. Maybe you could make a quick video and share it with us? 🙂
