The queen loach is a striking fish with a calm demeanor. It spends most of its time near the tank bottom, eating snails and small food particles. Easy to care for and adds a nice visual element to the tank. I’ve kept it for over a year and it’s still active and healthy.

It’s a beautiful fish that fits well in a community tank. I noticed it gets slightly territorial when kept with more than one, so I now keep it alone. Feeding it a mix of sinking food and snails keeps it happy and active.

I bought this loach for my 30-gallon tank. It’s very easy to care for and doesn’t stress other fish. It’s active during the day and enjoys scavenging. The size is manageable and it looks great in the tank.
