Aquarium Advice FINatic
this is a weird way of thinking but i think a BN pleco would do great in a 20g tank, yes they do get to be around 5inches but mainly because plecos dont go around swimming that often, my BN pleco just tends to stay in his DW, so thats my way of seeing a pleco
but i would never put a common in though ^_^ they get way tooo big for me
For sure about the common plecos. I don't like their look anyways. I prefer the dwarf pleco varieties regardless of the size of the tank. The current BN pleco I have now is really young and only about 2.5 inches. She is pretty active and fights the other fish for peas on "peanight". I have alot of surfaces and natural driftwood in the tank too that she seems inclined to explore.
Here is a picture of the BN. As you can see, she is still really small. She is next to a sunset molly and a von rio tetra.
