Yo-yo loaches are the perfect addition to community aquariums! They do well in peaceful to semi-aggressive aquariums, but should not be added to an aggressive one. They grow to be about 2.5 inches and prefer to be kept in schools of at least 5. Yo-yo loaches spend their day sifting through the substrate looking for any food that they can find. If youre looking for a lot of movement in the bottom of your community tank, then these are definitely worth a look into!
