CuteAngelfish Posted November 28, 2021 Share Posted November 28, 2021 Hello so i have lots of wood laying around my backyard that has been dried out for 3 years now but the avocado wood has caught my eye for my 85 gallon. However i have read that there is a toxin called Persin in most of the Avocado plant. Its toxic in large quantity for dogs and cats but it says nothing on fish. I look it up on youtube and its just videos of people propagating the avocado pits in there aquariums with live fish. So could i use the wood if properly prepared?
