So I never really see my khuli loaches, but my tank is pretty new still, and I've heard this is common.
The khulis spend nearly 100% of the time I can see them (maybe they come out while I sleep) hiding under
driftwood or in a cave (where you can sometimes make them out, other times not so much). VERY rarely will they hide under the stones in the forefront of the cave or in plants.
What I'm worried about is this:
I leave some pellets for them before I turn the lights out, and have plenty of food I leave at the bottom (some smaller pellets that all the fish eat, algae pellets mainly for the pleco, and the shrimp pellets for the loaches). The pleco is an eating monster and a huge pig. I'm worried that he's eating all of the loaches food and kind of out competing them for food. Also, the ghost shrimp are consistently out and get their fair share. Now, with leftovers from other fish never being their the next day, and no food left on the bottom, I'm sure the loaches eat - but I never see it so I'm a hair worried.
Any advice on this?
Here's a pic of my tank setup. You can see where they hide (driftwood on the left, cave with the wheel on the right). They're rarely out.
