i recently picked up a few zebra plecos and have been keeping a clos eye on them. i have noticed that all but one likes to spend it's time inside a cave and the one chills above the cave which has a slate canopy over it.

is it too early to observe them? the ones in the cave are the bigger ones ranging about 1.25-1.5", the one up top is about an inch. im hoping its too soon to observe them as such cause that would mean i only have one female.

any opinions or such is appreciated.

They are too young to tell, and it is not that "black and white", meaning "if one likes to be in the cave he is a male". Feed them well and wait untill they are 1,75 to 2 inches, then you can start quessing their sex.

good thing as i was hoping you cant observe too early on because shortly after all of them were in the cave.
