LOL!The zebras are poop machines, food goes in one end & straight out the other.
Never seen so much poop since I added one to one of my Betta tanks.
Trumpets you'll hardly see as they tend to come out once the lights are off
I just want to see their shells if they leave those out of the sand. I might watch during the evening though.
At some point my plant should extend along the lighter part of my tank, thus efficiently producing oxygen, consuming toxines and providing shade and shelter for the fish. So the trumpets might come out still.
Side note: it's so easy to clean the sand with the net. Even fish poop gets easily hoovered by the net, not just plants.
