I bought two fish labelled as black otos a couple of months ago, and finally got a decent photo of one of them. Looking on planetcatfish, I think they're hisonotus leucofrenatus, but not sure - would appreciate confirmation from anyone with more experience?
They spend most of their time stationary on a leaf, bogwood or flat stones, occasionally on the glass. When they do move, they dart very quickly across the tank and settle in a new spot. They eat algae, but can't keep up with the supply in my tank. They also like cucumber. They don't appear to interact with each other at all (or with the other fish in the tank) - so far they've been completely solitary creatures. When added to the tank, they started eating straight away, and so far haven't shown any signs of being unhappy in my hard alkaline water (pH 7.9), though of course it's early days. They were very small when we got them, and have grown noticeably since they arrived, but are still only about 2cm long.
First attempt at uploading a photo, so hope this works!
