I'm hoping one of the thinner ones ate the pellets. The two thicker ones each had a small lump in their bellies when I got them. When my guy got them to the store he had an employee put them in a tank and mark them with do not sell, sold. The guy put them in the wrong tank lol. He did mark them correctly. He put them in a tank with Mexican dwarf orange crawfish.......lol My guy said at least they have been eating well about half the population of crawfish were gone since Thursday he had 25 when they went in sold about 5 about 10 left.
