I HAD at least 6 oto cats in my 90 gallon and 3 in my 33 long. I saw one of them in the mouth of my Geophagus Bahi reds in the 33 and he was the last one. Then I looked in the 90 (that has a Geo. jurupari, 2 TF barbs and 2 L-200's) and those were gone also! I liked the way they cleaned the glass and I'm afraid they became sushi! Any help?
