I have had a upside-down for a year, it's a really cool fish to watch. When it goes to eat it flips over, it's head is white. It loves to hide under a log I have. Definitely they need a spot to hide.
I love these unusual fish. They are like this because, in the wild, these fish lay under lily pads upside down to watch for predators and large frogs. They are great fish that love lily pad plastic plants. They are wonderful fish. I recommend them.
I have 2 in a 60 cm tank. They are great to watch, but I hardly see them unless I turn off the light for a few hours, and then they should come out. They are easy to look after, but I've never seen them eat!
These fish are easy to care for. They look silly in the pet shop as they all swim upside down and play around together in the empty tanks. However, in a planted tank you will rarely see them, as they hide all day. In my tank, with a hollow bit of driftwood, I did not see him for over 4 months!
I've had a pair of upside down catfish for just over a year, I got them pretty young and they have grown so quick it's not funny. They have a brilliant colour and a very peaceful with other fish but they are very territorial with there own kind. It is still best to keep them in a small shoal of maybe 4 if you want to breed them.
I recently purchased a fully grown upside down catfish from the pet store in which I work. I was surprised to see that the fish would not eat the shrimp pellets or the sinking food, he would actually come to the surface to eat the flake food. How peculiar! Well, as far as temperament goes, he's amazing. Mine gets along very well with my large fish, however he is more than 10 cm. He's actually 12-13 cm which is abnormal, I've been told. However, nothing is abnormal when he eats flake food. The tendency is to hide out in the tank during the daytime, and be a little more active during the evening, which is the time I tend to be nearest my tanks.
