Ok I have a Iridescent shark (about 7") for adoption due to the fact that it is too shy to get the food fast enough in my aquarium. It's still healthy but it's no longer as fat as before so I need to find a new home for it.
It is a quick moving non-aggressive fish which mixes well with a wide variety of fishes. Shy too. Eats standard food but seems to like sinking tablets meant for pleco. Very hardy fish. It can grow very large but I had mine for over 2 years in a 3 feet tank and it's growing very slowly.
Errr we locals know it as the bating fish too ><
Please PM me if you are interested in adopting it
Sorry I don't have a picture of it but you can refer to the link below
