Hello all! Just a quick question here. I have a 10 gallon with 1 female betta and 2 snails. I really want an Upside Down Catfish but a Petsmart employee told me that they sting people. Will one hurt my fish? Thanks!
I have several of these. Synodontis nigriventris.
They don't sting as far as I know, but they do get a bit large for a 10 gallon.
The ones I have (from PetSmart) started out as 1" long fish. Fast forward two years, and they're approaching 3". I believe they top out at around 4"
I suppose you could keep one in a 10 gallon, but they are happier in groups of at least 3-4.
The upside down catfish has more of a chance of stinging you then other fish. If the other fishes cannot attemp to swallow it, this cannot happen.
