So I've been scratching my head for the last month or so as I noticed the Bolbitis in one my tanks started looking deformed. I've always done a high-end EI type dosing so I was very confident that nothing was running short and the tank has been running the same way for around three years. Upon closer examination it actually didn't looked deformed by stripped/eaten. I started doing some research and hit upon an Article in TFH concerning Amanos and how they can rid a tank of algae, BUT when the algae runs out since they are herbivores they will still nibbling on certain plants. One of the plants mentioned that the Amanos were fond of was new shoots of Bolbitis. I never had the problem prior to the Amano addition so I feel pretty confident after reading the Amano article that this is the problem. I often wondered why Amano always introduced shrimp to deal with startup algae and then removed them.
