My two Cats are playful and they do not need hiding places as mentioned in an earlier comment. They usually tend to stick out in the open waiting for a chance to swallow any pellets or small guppy feeders I toss into the tank. They are easily frightened though. And they´re not very active when they´re hungry. They are greedy and they have humungus appetites. They are very delicate though. I tried to catch one in the net and its sharp dorsal fin got caught in the fibers and I had to cut the edge of its fin off, but it knew I was only trying to help and didn't splash around. It stayed calm. And another delicate thing about them is the feeding. If they miss a meal they might lose their appetite for a long time (I don't know about yours but that´s what happened to mine) and their bellies look pinched in.
I have had great success with Pictus Cats. I currently have one now that is about 13 cm. They are great catfish for anyone witha cichlid tank. They adapt well to the high pH and water hardness. I have my Pictus and a good sized Spotted Pleco in with a community of African Mbuna Cichlids. The Pictus is thriving. He holds his own at feeding time and refuses to be bullied by any cichlids. He swims freely and happily through any of the cichlids´ territory and really goes nuts around my airstone at night. I recommend these fish to anyone looking for a bottom feeder to put in with any aggressive fish.
I had two "Pim Cats" in my 200 L aquarium. They did very well, although one with darker spots didn't grow beyond about 8 cm, the one with lighter spots grew to nearly 35 cm before they both developed some type of bacterial or fungal body rot that I could not cure. I bought the two separately and they got along well with all the other fish in the tank. I suppose there are different species or slightly different variations from different regions, as they were quite different in appearance.
I would like to warn you that when picking Pictus Cats, get them at a decent size. Babies are known to swallow food whole and choke on it, and there is nothing that can be done. Also my male Pictus will lose his barbs and then they grow back, it's happened twice. Two little stubs sticking out of the side of his face. But I have to get rid of him as he had a female that fell ill and died, and ever since then, he has been miserable. I tried to introduce another female but he ignored her, and being too small, choked on food and died as a result, making him even more miserable. The only fish he likes now are the Cory Cats. When they get to full, the Pictus lays in front with them and they stare at each other as if to say what the heck is wrong with him!
I have had my Pictus cat about four/five years now and he has grown from about 7 cm to about 13 cm. Very hungry but fairly docile fish. Over the years my tank (100 L) has become kind of space on residents. Actually, I only had the Pictus and one Jewel tetra left. I had several Jewel tetras but they "seem" to have vanished over the last few months. The Jewel tetras were also about four years old and I just figured they died and the catfish ate the remains; I couldn't find any sign of them. Well, last Sunday I purchased two more Jewel tetras and three swordtails (about 5 cm). Monday morning I was missing a sword. Okay, call me dense but I figured "new fish, probably didn't make it and the cat ate it." Tuesday morning I am missing my male sword. Okay, I may be slow, but that cat is eating my other fish! I came across this site while pondering what to do with him and just thought I would add to the posts and warn people that although this is a very pretty cat, it will eat good sized fish.
I've got two in my 180 L tank and they love the bubbles. Through past experience they do need a good oxygen supply, and often gasp and breathe heavily if the air pump is switched off for a prolonged period if I'm cleaning the tank. Once, when I was cleaning the tank, one of them got scared and brushed passed me. Its fin caught my finger. It was really sore and felt like a bad bee sting. It swole up through the day, but within two days it was gone. I'm now a bit more careful when rumaging around.
