Love these! Super cute little clean up crew.
My order of Kuhli Loaches arrived alive and healthy, and have acclimated well to life in my aquarium. They only make the rare appearance during the day and are quite skittish, but when they do come out of hiding they are a real treat to watch. The substrate in my tank is pea river gravel and I have been amazed at how easily and quickly they can burrow through it. I have observed one burrowing down on one side of a clump of micro sword and popping up on the opposite side nearly as soon as it disappeared from view. That said, they do sometimes uproot plants, so bear that in mind if it is a concern to you. These fish will eat practically anything you feed the other inhabitants of the tank, including algae wafers, and seem to have very big appetites. They do appear to have a high growth rate, which may contribute to their healthy appetite, so idk if that is true of mature specimens. Overall I am very pleased with these fish and the job they do cleaning up whatever food makes it to the substrate.
Love my black kuhlii loaches. They and other fish I ordered came last Friday and were and continue to be super healthy and robust eaters. So pleased with my purchase!
