Will you take a 6 inch-ish iridescant shark? Also, 3 monsters I thought were cory cats when I bought them new to the hobby a couple of years ago but definitely are not. I think they are a type of syno. cats, I seem to remember they started with an m and sort of sounded like methusalah and I thought maybe they'd live a long time. They look a little like upside down catfish but tend to hang out at the bottom wedged in a tiny space in the driftwood or next to the heater. They are probably 3-4 inches long.
thanks,
Jackie
