Another thing to keep in mind is that the bottom feeders are not very good at competing for food. This means that if you have other fish in the tank, you will need to make sure they are getting enough to eat before the bottom feeders. One way to do this is by feeding the other fish first and then giving the bottom feeders whatever is leftover.

Finally, it is important to remember that the bottom feeders are scavengers by nature. This means that they will often eat anything they can find, including live plants. If you have live plants in your aquarium, you may want to consider giving the bottom feeders their separate areas to prevent them from destroying your plants.
