I just recently discovered this amazing creature called the "blob fish." I was trying to figure out how it reproduces. Because apparently it doesn't swim, it just floats around and eats things that come in front of its mouth.
Thanks for the help!

Here is information on breeding by blob sculpins.

Aggregations of Egg-Brooding Deep-Sea Fish and Cephalopods on the Gorda Escarpment: a Reproductive Hot Spot -- Drazen et al. 205 (1): 1 -- The Biological Bulletin (http://www.biolbull.org/cgi/content/full/205/1/1)

I edited from the link above to give you some information easier to read...

Blob sculpin attended nests of 9000 to 108,000 pinkish eggs. The majority of the nests had brooding fish within 10 feet, often sitting directly on or touching the eggs. Some nests and fish were observed by themselves primarily in the roughest terrain where it was difficult to see behind nearby rocks and ledges. The eggs were free of dirt, suggesting that the adults regularly cleaned or fanned their nest sites.

Brooding fish were almost always found very close to each other, and nests were often on neighboring boulders separated by only 1 or 2 meters. Generally the parent fish did not move when the ROV [an underwater machine] approached; however, this was also true for fish with no eggs. The sex of the fish could not be determined from video observations.

The eggs were generally laid on the flat exposed surfaces of large boulders and rock outcrops. Of the 64 egg masses, 57 (89%) had been laid on single rocks; the other seven were each strewn across as many as three neighboring rocks or across large fissures in a flat rock face.
