Ok, so I have finaly got my betta makeing a bubblenest, it is smale but thick, and he has small bubbles lined around the rim of the 1 gal. bowl. how big dose the bubblenest need to be? I have breeding grass in the bottom of the fish bowl, and plants, so that the fry can hide in it or the female can hide. can I grind up fish flakes to feed to the fry, of crunch up the blood worms or the pelets... thank you for answereing my other questions.
