i saw these cute little catfish titled as banjo cat fish iwant to know how big thaey get and if theyed be good for a 10 gal and if not what catfish would be good for ten gal
they get to between 4 and 6 inch i think, maybe wrong though. a small catfish similar looking would be hara jerdoni. aka asian stone or mini moth catfish
What are the dimensions of the tank? personally i would say its a bit on the small side but you might get away with it if it has a large footprint. If your wanting a catfish you will see a lot of the time i wouldnt get one though I have 3 in a 30G and i only really ever see one of them who will occasionally come out during feeding.
You really need to get a photo of them or confirm they are banjo cats before proceeding. Generally, the fish we see in the hobby are Bunocephalus coracoideus, but just occasionally they can be a mixture of other similar species, such as Bunocephalus colombianus or Bunocephalus verrucosus. There are a few other species that sometimes come up for sale, though the price is generally higher for these, such as Amaralia hypsiura.
I think I'm in agreement though with everyone else, these fish, although very sedentary, are not suited to a tank as small as yours.
