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!!!!! /huh.gif" style="vertical-align:middle" emoid=":huh:" border="0" alt="huh.gif" />

I didn't see him again until I did an ornament clean (I don't do this every water change as it is quite disruptive) 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! /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 /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> Since then I have seen him out every day stuck on the side of his house until a fish swims past then he dives back in again. This morning he was swimming around the tank, routing in the gravel without a care in the world! I seriously wondered if it was a different fish as it was so out of character for him /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 /blush.gif" style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" /> It's rather nice to be able to enjoy his presence in the tank!

Hey Kitt

This can happen with Synodontis. My article on Synodontis albolineatus is still on the Scotcat website (www.scotcat). Have a read as the albolineatus stayed 'out of vew' for 12 months before starting to make 'regular appearances'.

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.

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 /laugh.gif" style="vertical-align:middle" emoid="Laugh" border="0" alt="laugh.gif" />

I think I am right in saying that true nigriventris are still considered a seasonal fish and usually appear in shops in any numbers early in the year, so either the shop you purchased yours from had some left over from an early shipment or like Matt says it could well be one of the many species of Synodontis sold under the label of Upside down catfish.

Hiya

as "Oscar" was out again this morning, I tried to get a picture of him (I'm sorry it's not very clear) so that you could maybe tell me what type he is!

Try putting your camera on macro settings and take lots n lots of pics lol A little video snippet might be easier if you struggle with a photo /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

I've managed to find a pic on the web that looks very much like Oscar! Hope this helps /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />

YAY /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! /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

That would suggest to me that it's not a nigriventris (again)... /rolleyes.gif" style="vertical-align:middle" emoid=":rolleyes:" border="0" alt="rolleyes.gif" />

Hey

Another angle? In the U.K. we have seen a fish known as Synodontis nigriventris 'black' (not to be confused with the Syno. 'species black marmoratus', which we pictured alongside albino Kribensis in Aquarium Gazette Issue 8's beautifully illustrated article on Kribensis) which is not a true nigriventris but a hybrid (possibly with nigrita?). Could this be Kitt's fish?

Hiya I have another pic for you - I hope this is easier for you to see better. /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />

I found him attached to his "house" with his nose down & his tail up - this is how he likes to be.

So do I have the real thing or is it a good fake /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

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 /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Hey Kit

Without seeing the fish 'in the flesh' I think it is the sub-specie Synodontis nigriventris davidsii (genuine, no joke, but someone on a different website, a couple of years past, thought I was not taking their thread seriously and 'having fun'). This fish was once scientifically classed as a specie in its own right. A beautiful fish which grows a little larger than 'normal' nigriventris and one which does not stay upside down for long periods of time.

Hi David

I can see how they may have been confused /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> LOL
I did try googling this but it only gave me the normal variety - so how big do these variety grow? I hope my tank is big enough /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" />

Hey Kit

Don't worry as, if your fish is as above, only, on average, about 7cm larger than the normal variety.
