It’s beneficial to add a few bottom-feeding fish to your aquarium because, as their name implies, they graze along the bottom of your aquarium. Down there, they’ll eat algae, as well as food that has settled to the bottom of their aquarium. For one, this saves you from having to vacuum the substrate of your aquarium as often, and in some cases, may even entirely relieve you from your duties as Algae Scrubber.
But anyways, the five best bottom-feeding fish are:
Corydoras Catfish are a great place to start when you’re thinking about getting your first bottom-feeding fish.
(1) These fish are very adaptable to water conditions. So, if you’re fairly new to the hobby, or you’re found yourself to let water conditions slide a little bit, these guys might be a good bet.
(2) Corydoras Catfish are one of the few catfish that aren’t considered nocturnal. This gives you a chance to keep a catfish in your tank and get to enjoy its amusing behaviors for once.
(3) These fish breed like crazy. So, having them in an aquarium makes it very easy to observe the breeding process of fish if you have struggled with it in the past.
If you’re on the hunt for an awesome bottom-feeding fish, it’s hard to beat the Bristlenose Pleco.
(1) The Bristlenose Pleco eats like a giant. As soon as you put one of them into your aquarium at home, you can pretty much consider your algae problems gone.
(2) These guys love to eat other food besides just algae and algae wafers. They actually quite enjoy eating tons of vegetables. Placing cucumber, squash, green beans, or peas into their aquarium can be an interesting sight to watch.
(3) They are a convenient size. Since they only grow about 4-6 inches, they’re in that sweet-spot zone to be large enough to not be threatened by large fish, but small enough to live in a smaller-sized aquarium.
The Clown Loach is a very popular choice when it comes to bottom-feeding fish, and for good reason.
(1) They are very social fish. If you walk up to their tank, they’ll usually observe and respond to you in some entertaining way instead of just swimming around.
(2) They have very entertaining behavior when their among other fish. As a matter of fact, some fishkeepers have even reported that their Clown Loach will play dead at times.
(3) They grow at a quick pace. Eventually, you’ll walk up to their tank and realize that they aren’t the small, little Loach they used to be when you first brought them home.
Although the Kuhli Loach isn’t as popular as the Clown Loach, it’s still a very good choice when it comes to selecting a bottom-feeding fish.
(1) These guys will add some variety to your tank’s appeal. Yes, they are fish, but c’mon, they look like eels.
(2) Their bio-load is much smaller than the average Loach. So, keeping some of these in your tank will get the cleaning job done, and will require less water changes to do it compared to other Loaches. Can’t argue with that.
(3) Their health is easy to care for. Since there are no Kuhli Loach-specific diseases, they’re less prone to health risks than other fish usually are.
Tiger Shovelnose Catfish
The Tiger Shovelnose Catfish is an awesome bottom-feeding fish for any advanced fishkeeper that has a very large aquarium.
(1) This fish is massive. It can be a hassle if you’ve got a small aquarium at home but, if you’ve got an aquarium that’s 300-gallons or larger, it can be beneficial. Having such a large bottom-feeding fish in your aquarium will mean that less bottom-feeding fish are required in your aquarium to keep the bottom of your aquarium clean.
(2) These fish are very hardy. Yes, it’s always recommended you keep their water conditions at their ideal range, but the Tiger Shovelnose Catfish can withstand severe fluctuations in temperature without being affected whatsoever.
(3) These fish are very entertaining to feed. You can actually feed them bits of hot dogs, chicken, or turkey. They love them all!
