The other amano climbed out too! I found it under my son’s toy car...Are they notorious climbers? I had disconnected the CO2, also done 3 water changes in the past 5 days. I tested the water just in case, NH4 is 0 and NO2 0,05 (but I don’t trust this test really, it is out of date and always gives the same result, also on tap water). TDS matches the tap and the temp is 26,5. Nothing alarming I’d say...
I’d like to keep the tank open but don’t want to find livestock on the floor...Do cories and otos jump?
Can't speak for Amano shrimp but Rednose Shrimp and NQ Algae Shrimp have done a lot of jumping onto my floor. Otocinclus have not dropped but will sometimes gulp air like a Corydoras. It isn't super common for Otoclincus to do this and in my experience if they keep doing it something could be wrong.
