Common Pleco VS Oto

[dnsfpl]

is this the way to identify m or f for oto?

[Aquaria One]

stick to octos

Yer, i think thats how you sex them. Putting it into practise is harder than you think xD haha

[dnsfpl]

male is slightly easier
as for the female, i still cannot confirm
maybe it is a more well fed male haha

[Verminator]

Yes, i wouldnt advise trying to distinguish the two after feeding time xD May prove quite awkward, or you'd be led to think you had a male and female one day, the next you may think he's had a gender change over night
