We have 3 of those here in the city that have been 4 sale for almost a year now, no one wants them because they cannot go with anything. And from seeing them on a weekly basis as all 3 have their own 90 gallon tank, they just sit there doing nothing in the corner. Very boring fish IMO and they look just like a Marbled PIM, just Black. And at least the Marbled Pim can go with other fish, my 2 footer lives with 3 inch fish and never bothers them.
Either way $40 is a bargin, the 3 we have are going for $80 per fish, and they are a bout 10-12 inchs now.
