Front faced gills and lots of poop.

[Jessiemccrary]

Hi everyone. So I’ve got two 3-4” juveniles and both have front facing gills. No matter what I do, they stay like that. Water levels are great, regular changes, eating one cube of bloodworms everyday between the two of them and the only thing I’ve noticed is they poop SO MUCH. Like small piles all day everyday. Is this normal??
