Mushrooms dont take over your tank they just grow well, kenya trees take over your tank! And i have multiple types of mushrooms and they grow slowly and controlled under my ai blues , acans are over rated and not so easy to maintain at times , nice yes , expensive ? Yes , easy to keep ? NO!!!
You are entitled to your opinion but dandilions are also nice and they are still considered weeds. 'Acans are over rated' by who? 'and not so easy to maintain' what is it that you have to do to maintain them? 'at times , nice yes' I will accept that. 'expensive ? Yes' compared to mushrooms maybe but compared to all the other corals being sold here I would say they are cheap. 'easy to keep' yes-all you do is put it in the tank. yes you can feed them and they will grow faster but they are fine as is. And they don't go floating around killing other corals as mushrooms do. And yes at times a colony will just die on you but I have had that with mushrooms as well.
