they look like buruse root to me have they been beat on by you or your fish
Thanks so much. ok so i trimmed the rot but because it had already spread all the way through about 95% of the rhizome do you think it will survive with just a little pimple-sized bump f a rhizome? im gonna upload a pic in just 1 min hold on a sec here.carefully cut out the rotted section then softly plant then. Also remember that unless you have a co2 injection system you can only have as many plants as your fish produce waste to feed.
