My bottom feeder are.
14 bronze cories.
2 baby albino cories.
4 melina cories
The cories are awesome.
I have 4 weather loaches(3 gold, 1 common)
These guys are good cleaners too, plus they dig and go under the gravel.(good if you have no plants where they dig, bad if you do.)
2 yoyo loaches. Ok ..when the food is out.Do dig for some food when it isn't.
I wouldn't get a pleco, unless you go with a gold pleco, or a pleco that doesn't grow large.I perfer ottos to plecos.
I have 10 ottos(6 in a fully planted 30) 4 in my q-tank.
I have 6 plecos, which eventually I will get rid of.
