Haven't had that problem yet they just started eating massivore and they like wait at the bottom in tere corner there lazy it's wierd. I think they think there geos they'll eat off the sand lol damn bad influence dithers!
I tried putting a ping pong ball at the top so maybe they would hit that instead of the hard plastic. What a mistake lol they got terrified and they have been in hide stress mode for like 12 hours now. Guess I'm never doing that again...
