Any Bottom Feeders That Can Be Alone

[Sasha123]

I have another tank(20 tall) I'm setting up, it will be awhile before its ready though. I want a guppy tank, I love guppies. Are there any bottom feeders that I can keep single or pairs, with a gravel bottom and hard water? I know that's a lot to expect but thought Id ask.THX

Plecos can be kept alone but you have to be careful to get a species that stays small. Most plecos will outgrow a 20 gallon but there are some species that will stay 6 inches and under.

Clown plecos and dwarf bristlenose plecos remain small.

Most people say that a bristlenose pleco will not do well in a 20 gallon but mine has been doing fine so far. (I got her without research, my bad, I know). However, with a bn pleco, the problem is more the bioload than the size. My tank is moderately planted with a heavily modified filter to keep up with my bioload.

So, I haven't had issues with the bn so far as far as aggression or health but shes's still growing, only 3 or 4 inches. And I have to sneak her food past my mollies at night.

A mystery snail would keep the bottom clean.

I might go with a snail, I don't want a big bio load..I would love shrimp but not sure if I could keep them alive they look so fragile

My favourite in this application. Mine lived for six years. You need to make sure bottom feeders actually get some food, especially with active fish like guppies.

Amano shrimp are very tough
