My favorite freshwater fish are kuhli loaches. They have such cute personalities and because of their eel-like body shape they can do things that a lot of other fish can't do, such as hanging from the plants in the tank like snakes.
I have a cave in my kuhli loach tank where I keep about 8 kuhli loaches. Because they like to congregate together they are usually all in the cave together at one time. When I feed them something they really like, such as mysis shrimp, they all come swimming out of the cave at once and it is really something to watch. It looks like a swarm of small snakes.
Of course there are many other fish that I also like as well, but if I put down ALL of my favorites it would take me about three years to write this post.
