A friend of my grandma left me this tuber but I don't really know what it is. I think it could be a Sauromatum venosum, I know how to cure amorphophallus is this different? And, it's around 5 cm in diameter and 150 grams is it possible for it to bloom next year?
I have a lot of fryes that were born in august, winter is aproaching and in october it will start to become too cold, what can I do? Is an acquarium a viable option to grow them and for surviving the winter?
I keep my medaka in a big tub outside, the passed the winter well and at the start of spring they were thriving. They were 10 and now I can only see 5 of them and the one I see are very thin and don't eat. In the past I had sone of them do this and die without a real reason and they were incurable. The temperature and the water are alright what can I do?
