Good Bottom Feeders

[NeonNeptune]

I want to get some bottom feeders for my tank but want to get some hardy ones. I heard corries need sand substrate. Is this true or will they be okay with gravel. Also are there any good invertebrates that will be good? And they need to be okay with plants, thanks!

Is your gravel pea-sized and fairly rounded off? What size tank do you have? Thanks!

My tank is 20 gallons and the gravel is not that round and pea sized.

Do you have any wood in your tank? If so, may I suggest something like a Bristle nose Pleco or a Golden Nugget Pleco? Since your gravel isn't rounded off then I'm lead to believe it's quite sharp in places which sadly cannot accommodate quite a few species of catfish suitable for your tank size. The bristlenose pleco will grow to be about 4 - 5.5 inches long and the Gold Nugget will get to be about 6.5 - 7.5 inches long. They'll feed mostly upon algae in the tank and on the wood in your aquarium but their diet will need supplementing with sinking algae tablets.

EDIT: This is assuming that you're not currently at your stocking limit.
