I read somewhere some bettas will ingest the finer varieties of substrate? I would like to know if that's true or not. I do know during feedings, Bettas will INHALE food if there's other fish in the tank.
So tell me, is this something I should worry about or a pigment of someone's imagination?
I'm going to the supply yard to research the different types of inert forms of gravel today and hopefully bring back a giant bag over the weekend.
Any input would be helpful.
