I bought one of these little critters (Upside down catfish) in October 2008 because they looked kinda cool – swimming upside down! I put “Oscar” in his new tank & he immediately went & hid inside one of the ornaments & stayed there!!!!!
 I really thought he had died as I hadn’t seen him since that first day, but when I took the ornament out he plopped back into the water! I was quite surprised to see him alive – considering he shared his hiding space with my large sucking loach! <img src=)
/blink.gif” style=”vertical-align:middle” emoid=”:blink:” border=”0″ alt=”blink.gif” /> I paid £5.99 for him & was beginning to think that this was a waste of money for a fish I never see!
However, the other day I spotted him out of his “house” for the first time during the day, & on the side of it staying very still – as soon as I moved he disappeared back inside
/ohmy.gif” style=”vertical-align:middle” emoid=”:o” border=”0″ alt=”ohmy.gif” /> So any ideas on the sudden change in behaviour? (6 months of hiding to being out & about over night) not that I’m complaining of course
Hi Kit just to add to what David has said my hunch is you don’t have an upside-down cat S. nigriventris but one of those sold with the name like S. nigrita or similar.
S. nigriventris.
Juvenile S. nigrita. Pic credit: scotcat.com
I have 5 large true nigriventris in my 250 gallon tank and for the first month or so they were out and about all the time but I am lucky if I see 1 a week now, I catch glimpses of them under the bogwood but they rarely venture out into open water when the lights are on to the point where occasionally I forget they are even in there
Hi Kit, i’m at the same feelings it’s not the S. nigriventris. aswell. I’m really sorry but i can’t tell from this photo. Could you try another photo please

Hope this helps
That is one of my nigriventris
Lmao @ omnipresent Mark!

/biggrin.gif” style=”vertical-align:middle” emoid=”:D” border=”0″ alt=”biggrin.gif” /> So now that we have that cleared up – why doesn’t he swim upside down any more?
Since “Oscar” started showing himself, he’s either stuck to the outside of his house or he swims (the right way up) skimming over the gravel in search of food. Even if he gets spooked he still swims the right way up (all be it very fast!)
Hmmm maybe sharing his “house” with a sucking loach has given Oscar an identity crisis!
That would suggest to me that it’s not a nigriventris (again)…
Hiya I have another pic for you – I hope this is easier for you to see better.

That looks like nigriventris to me, mine don’t swim upside down all of the time, they are only really upside down when hiding or at rest or swimming in the upper areas of the tank, obviously when feeding which is the most common time they are seen they have to swim with mouth downwards.
Personally I would try and find some more and add at least a couple more
